WebOther classifications depend on characteristics that are relevant to the manufacturing process or designing of the product. Examples of such qualities and classes are conductive polymers, thermoplastics and thermosets, engineering plastics and biodegradable plastics and other similar plastics with unique structures, such as elastomers ... WebPolymer types. There are 3 principal classes of polymers – thermoplastics, thermosets, and elastomers. Differentiation between these classes is best defined by their behaviour under applied heat. Thermoplastic polymers can be either amorphous or crystalline. They behave in a relatively ductile manner but often have low strength.
WebDec 25, 2015 · Polymers can be classified based on their origin as natural or synthesis. Other texts have classified polymers according to functions, source, polymerization mechanism, polymer structure, preparation techniques, and thermal behavior.

The reaction is done at high pressures in the presence of a trace of oxygen as an initiator. Some common addition polymers are listed in Table 27.8.1. WebPolymerization is a process through which a large number of monomer molecules react together to form a polymer. The macromolecules produced from a polymerization may have a linear or a branched structure. They can also assume the shape of a complex, three-dimensional network. There exist several different categories of polymerization reactions ...
