Question
When condensation product of hexamethylene-diamine and adipic acid is heated to $$525\,K$$ in an atmosphere of nitrogen for about 4 - 5 hours, the product obtained is
A.
solid polymer of nylon 6, 6
B.
liquid polymer of nylon 6, 6
C.
gaseous polymer of nylon 6, 6
D.
liquid polymer of nylon 6
Answer :
liquid polymer of nylon 6, 6
Solution :
The condensation polymerisation of hexamethylene diamine and adipic acid is done in solution form by interface technique. In this, liquid nylon polymer is obtained.
