Answer the following in brief.

Question

Explain the classification of polymers on the basis of structures.

Vidyadip · Accepted Answer

Depending upon how the monomers are linked together, that is, the chain configuration, polymers are classified into three types:

Linear or straight chain polymers: When the monomer molecules are joined together in a linear arrangement the resulting polymer is a straight chain polymer. It is obtained from bifunctional monomers or alkenes.
e.g. PVC, high-density polythene.
Branched chain polymers: Monomers having 3 functional groups or already having side chains give rise to branched chain polymers.
e.g. Low-density polythene.
Three dimensional cross-linked polymers: Third type of arrangement is said to be cross-linked or network polymers where cross-links are produced between linear chains. Cross-linking results from polyfunctional monomers.
e.g. Bakelite, melamine.
