The synthesis of which of the following polymers involves the repeated loss of small molecules? a) Polythene b) Buna-S c) Buna-N d) Nylon-6,6

The synthesis of which of the following polymers involves the repeated loss of small molecules?

a) Polythene

b) Buna-S

c) Buna-N

d) Nylon-6,6

Expert Solution

Answer : d) Nylon-6,6

Explanation :

Condensation polymers are formed by repeated condensation reaction by loosing small molecules of water and alcohol.

Nylon-6,6 is formed by the condensation of adipic acid and hexamethylene diammine results in loss of water molecules.

HOOC-(CH3)4-COOH + H2N-(CH3)6-NH2 --> Nylon-6,6

d) Nylon-6,6
