How are polymers classified on the basis of structure ?

Explanation

On the basis of structure of polymers, these are classified as :
(i) Linear polymers e.g., polythene, nylons, polyvinyl chloride, etc.
(ii) Branched chain polymers e.g., low density polythene, glycogen.
(iii) Cross linked polymers e.g., bakelite, melamine, etc.
