Polymers Question 28
Question: When condensation product of hexamethylenediamine and adipic acid is heated to $ 553K(80^{o}C) $ in an atmosphere of nitrogen for about 4-5 hours, the product obtained is
[DCE 2002; MHCET 2004]
Options:
A) Solid polymer of nylon 66
B) Liquid polymer of nylon 66
C) Gaseous polymer of nylon 66
D) Liquid polymer of nylon 6
Show Answer
Answer:
Correct Answer: B
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. $ n.H_2N-{{(CH_2)}_6}-NH_2 $
$ nHOOC-{{(CH_2)}_4}-COOH\underset{-nH_2O}{\mathop{\xrightarrow{Polymerisation}}} $
$ {{[-HN-(CH_2)_6-\underset{Nylon}{\mathop{NHCO}}-(CH_2)_4-CO-]}_n} $
