Which one of the following structures represents nylon 6, 6 polymer?

  1. [figure]
  2. [figure]
  3. [figure]
  4. [figure]

Answer

(4) [figure]

Solution

Nylon 6, 6 is a polyamide prepared by condensation polymerisation of hexamethylenediamine with adipic acid under high pressure and at high temperature:

nHOOC(CH2)4COOH + nH2N(CH2)6NH2

553 K, high pressure - [NH(CH2)6NH-CO(CH2)4CO ]n - + 2nH2O

The repeating unit contains six carbon atoms from the diamine and six carbon atoms from the dicarboxylic acid joined by amide (-CO-NH-) linkages.

In option (4), the unit -CO-(CH2-CH2)2-CO- = -CO(CH2)4CO- comes from adipic acid and -NH-(CH2)6-NH- comes from hexamethylenediamine, joined by amide linkages.

The structures in options (1), (2) and (3) are addition polymers of substituted alkenes with no amide linkage.
