How many polymers are co-polymers?

(i) Buna - N (ii) Buna -S (iii) polythene

(iv) Nylon - 6,6 (v) Teflon (vi) Terylene

(vii) Starch (viii) Cellulose (ix) Polystyrene

Answer:
4
Solution:

Solution:

 

A copolymer is formed from two or more different types of monomers.

(i) Buna-N: Copolymer of 1,3-butadiene and acrylonitrile.

(ii) Buna-S: Copolymer of 1,3-butadiene and styrene.

(iii) Polythene: Homopolymer of ethene.

(iv) Nylon-6,6: Copolymer of hexamethylenediamine and adipic acid.

(v) Teflon: Homopolymer of tetrafluoroethene.

(vi) Terylene (Dacron): Copolymer of ethylene glycol and terephthalic acid.

(vii) Starch: Homopolymer of glucose.

(viii) Cellulose: Homopolymer of glucose.

(ix) Polystyrene: Homopolymer of styrene.

 

Thus, Buna-N, Buna-S, Nylon-6,6, and Terylene are copolymers. There are 4 copolymers.
