Solution:
- (d) Copolymer of adipic acid (6C) and hexamethylene diamine (6C).
$ \begin{aligned} & n HOOC(CH_2)_4 COOH+nH_2 N(CH_2)_6 NH_2 \to \\ & \text{ Adipic acid } \\ & \text{ Hexamethyl ene diamine } \\ & \stackrel{.\stackrel{O}{C}-(CH_2)_4-\stackrel{O}{C}-NH-(CH_2)_6-NH) _{n}}{\text{ Nylon-6,6 }} \end{aligned} $
