Question

Identify the copolymer from the following:

(a) [CF_2-CF_2]_n

(b) [CH_2C(Cl)=CH-CH_2]_n

(c) [CH_2CHCl]_n

(d) [CH_2-CH=CH-CH_2-(C_6H_6)CH-CH_2]_n

Solution

Copolymer is defined as polymer made up by reacting two different monomers.

[CF_2−CF_2]_n is made up of tetrafluoro ethane only.

(b) is made up of CH_2C(Cl)=CH−CH_2 units.

Similarly (c) is made up of only one monomer that is CH_2CHCl
(d), however, is made up of [CH_2−CH=CH−CH_2] and [C_6H_6−CH−CH_2]
