classification of polymer based on monomer

E.g. Polymer chemistry It is a branch of chemistry in which we study about polymers. Classification. Polymer nomenclature usually applies to idealised representations; minor structural irregularities are ignored. Thus molecules like ammonia, water, ethanol etc are not monomers. The polymers that ranked as most hazardous are made of monomers classified as mutagenic and/or carcinogenic (category 1A or 1B). The glass transition temperature of polymers determines the temperature at which the polymer mechanical properties of polymers change dramatically, when the glass transition temperature is slightly below room temperature the polymer behaves like an elastic material (elastomer), when the temperature is higher than the glass transition temperature the polymer behaves as a rigid material (thermoset). Source-based nomenclature can be used when the can be monomer identified. The polymerization of monomers into copolymers is called copolymerization. Based on Structure of Polymers: There are three different types based on the structure of the polymers. preparation of polymers. polymer,classification of polymers,polymerization,copolymer,polythene.PVC,polystyrene,polyester,polycarbonates,polyamides,nylon6.6,addition ,isotactic This is one of the best Blogs for free tutorials about various parts of chemistry, such as element chemistry, organic chemistry, inorganic chemistry, physical chemistry, analytical chemistry, … Monomers are small and simple molecules depend and have a capacity of forming two chemical bonds with two other monomers. Anything that is made up of same type of Chemical composition which is repeated numerous times can be considered as a polymer. Among the properties that define the properties of polymers, the most important are: The glass transition temperature of the polymer. This process of formation of polymers from respective monomers is called polymerisation. Polymers: Lecture 2 Prepared by Dr Arunima Nayak and Dr Brij Bhushan Classification of Polymers 1. ADHESIVE & GLUE | The polymers are also classified based on: … Polymers are divided into three types on the basis of source of availability. Due to their complex structures, different behaviours, and vast applications we can, classify polymers based on the following criteria: under REACH. Artificial Polymers The polymers that ranked as most hazardous are made of monomers classified as mutagenic and/or carcinogenic (category 1A or 1B). There are a wide range of materials whose composition is based on polymers, all plastics, paint, coatings, adhesives, composites, etc ... these are examples of polymer-based materials we use in our daily life. 2. Natural polymers: These polymers are found in plants and animals. Most important addition polymers are polymerized from olefins and vinyl-based monomers. Classification of Polymers Based on Mode of Polymerisation derived from proteins or vulcanised oils, are classified in C08H. Copolymer - It is called when the polymer formed by at least 2 different monomers along the entire chain. Branched chain Polymers are linear polymers containing branches. Rubber bands and other elastics are made of elastomers. Addition, Videos and Examples Polymers: Classification, Polymerization, Biodegradable Polymers, Rubber. 1. These details include the overall chemical composition and the sequence of monomer units in the case of copolymers, the stereochemistry or tacticity of the chain, and the geometric isomerization in the case of diene-type polymers for which several synthesis routes may be possible. The average molecular weight directly determines both the size of the polymer and its chemical and mechanical properties of the polymer (viscosity, wet, creep resistance, abrasion resistance ...), for example polymers with high average molecular weight materials are very viscous. Derivatives of natural macromolecular polymers per se, e.g. A polymer is like a thread joins many coins punched through the center, in the end we get a string of coins, the coins would be the monomers, and the chain with the coins would be the polymer. Depending on the repetition or variety of monomers, polymers are classified as: Homopolymer - It is called when the polymer formed by the same monomer throughout its chain. Polymers can be classified by using the backbone of the polymeric chain, type of synthesis, source, monomer, molecular forces, etc. These linear chains are closely packed in space. Among the other properties that can be modified based on these factors include solubility in and other solvents, melting point, flammability, color, hardness, transparency, film thickness, wetability, surface friction, moldability, and particle size—the list goes on. Oligomer – a small macromolecule consisting of around 10 to 100 chemically bonded monomer repeat units. The process in which monomers are all linked together to form the long-chain polymers is called a polymerization reaction or polymerization process. For very high molecular weight, the solution process takes days or weeks. Quick summary with Stories. Each monomer that is added to form polymers is called repeat units. Structure of polythene. The urea-formaldehyde resin is a non-transparent plastic obtained by heating formaldehyde and urea. The monomer … In these polymers the monomer units are joined to form long chain with branches of different length. They can be subdivided into two broad classes, depending on the kind of the polymer that they form. All have a … Polyethylene Classification of Polymers 1. Classification: Classification Based on Source: [1] Natural Polymers: These polymers are found in plants and animals. 1.2 Polymer Structure. Homopolymer consist of only one type of monomers. Different types of polymers: 1) homopolymer 2) alternating copolymer 3) random copolymer 4) block copolymer 5) graft copolymer. Polyvinyl chloride 2. The addition polymers are generally prepared from unsaturated compounds. The simple molecules from which polymers are derived are called monomers. To stretch, the polymer chains must not be part of a rigid solid - either a glass or a crystal. The monomers in … The polymers which are prepared in the laboratory are referred to as synthetic polymers or man-made polymers. All simple molecules cannot behave as monomers but only those with two or more bonding sites can act as monomers. Classification of Polymer based on Structure. Polymer – a macromolecule consisting of at least around 100 chemically bonded repeat units. This process is slow because of cross-linking, crystallinity or hydrogen bonding. 2 mins read. 55 plastic polymers were ranked based on monomer classifications, and assessed. Agitation can speed up this process. Classification Based on Composition of Polymers. [2] Copolymer: When two different types of monomers are joined in the same polymer chain, the polymer is called a copolymer. For example;High density polythene,PVC, Nylon, Polyester. what needs to be done for notified polymers has been added (4 pages). Polymers obtained during condensation reaction are called condensation Polymers. Thermosets are strong and durable. [2] Copolymer: When two different types of monomers are joined in the same polymer chain, the polymer is called a copolymer. Natural polymers: They are naturally present within the bodies of the living organisms. Polymers are formed through chemical reactions that convert large numbers of low-molecular-weight molecules, known as monomers, into large, very high-molecular-weight long-chain macromolecules.Resins are compositions of either monomers or macromolecules blended with other components to provide a material with a useful set of properties. Based on the type of polymerization, polymers can be classified as: i) Addition polymers: These type of polymers are formed by the repeated addition of monomer molecules. Polymers are large molecules made up of alike repeating blocks known as monomers. Classification of polymers: Classification based on source of availability: 1. The functionality of monomers depends upon the number of bonding sites in monomer. What is polymerisa, Solubility process The dissolving process in polymer is very slow and occurs in two steps as 1) The solvent dissolves into the polymer to give a swollen gel. Therefore, cannot be classified under a single branch. In these polymers the monomer units are joined to form a long and linear chain. Polymers obtained during addition reaction are called addition Polymers. CLASSIFICATION OF POLYMERS : 1. Conveniently, all polymers can be assigned to one of two groups based upon their processing characteristics or the type of polymerization mechanism. This classification includes the following categories; Homopolymer: A homopolymer is made up of only one type of monomer. The word POLYMER comes from the Greek words poly means many and mer means parts . CONTENTS Introduction Types of Polymer Classification of Polymer Characteristics of Polymer Application References 2 3. These techniques are based on forcing a polymer solution through a matrix of cross-linked polymer particles at high pressure of up to several hundred bars. A polymer can be named in one of two ways. Artificial polymers: They are artificially made in industries for various commercial uses. Study Materials Classification of Polymers: Source, Structure, Polymerisation, Examples Types of Polymerization: Condensation vs. The small molecules that are used in synthesizing a polymer are called monomers. Classification Based on Composition of Polymers: [1] Homopolymer: A polymer resulting from the polymerization of a single monomer; a polymer consisting substantially of a single type of repeating unit. The process of converting monomers to polymer is called polymerization. That is, = and =, where for example is the rate constant for propagation of a polymer chain ending in monomer 1 (or A) by addition of monomer 2 (or B). Monomers can be classified in many ways. • Linear polymers have monomeric units joined end to end in single chains. 3] Based on Mode of Polymerisation Polymerization is the process by which monomer molecules are reacted together in a chemical reaction to form a polymer chain (or three-dimensional networks). It is called polymerisation higher density Co polymers a polymer is called Homo polymer the following some.
