Which one of the following represent nylon 6,6 polymer?

Options

A.
B.
C.
D.

Answer

B

Explanation

Nylon 6,6 (a polyamide ) is manufactured by the condensation polymerization of adipic and hexamethylenediamine. The acid and the amine first react to form a salt which when heated to `535 K` under pressure undergoes polymerization with eliminnation of water as steam and the nylon is produced in the molten state.
It can then be cast into a sheet of fibres by passing through a spinneret (some spinnign device). It is called nylon 6,6 (read as six, six) since both adipic and hexamethyllenediamin contains six carbon atoms each.
