15.2 Write the names of monomers of the following polymers:

15.2

Polymers are classified based on structure, into 3 types:

Linear Polymer: They have a long and straight chain of Ex: high-density Polythene, Polyvinyl chloride

Branched-chain Polymers: They have linear molecular chains along with some Ex: less density polythene.

Cross-linked or network Polymers: In these polymers, strong covalent bonds are between the linear chains. Generally, they contain 2 or 3 types of functional groups. Ex: Bakelite, melamine.
