When condensation product of hexamethylenediamine and adipic acid is heated to `553K(80^(@)C)` in an atmosphere of nitrogen for about `4-5` hours, the product obtained is

A

Solid polymer of nylon 66

B

Liquid polymer of nylon 66

C

Gaseous polymer of nylon 66

D

Liquid polymer of nylon 6

Text Solution

Verified by Experts

The correct Answer is:
B
The condensation polymerisation of hexamethylene diamine and adipic acid is done in solution form by interface technique. In this liquid nylon polymer is obtained.
