Question

The product obtained when condensation product of hexamethylenediamine and adipic acid is heated to $553K\left(\right.80^{o}C\left.\right)$ in an atmosphere of nitrogen for about 4-5 hours

• 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 1

Answer: (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.
$\text{n} \left(\text{.H}\right)_{\text{2}} \text{N} - \left(\left(\text{(CH}\right)_{\text{2}} \text{)}\right)_{\text{6}} - \left(\text{NH}\right)_{\text{2}} \, \text{+} \, n \text{HOOC} - \left(\left(\text{(CH}\right)_{\text{2}} \text{)}\right)_{\text{4}} - \text{COOH} \overset{\text{Polymerisation}}{ \rightarrow } \text{Polymer of nylon 6,6}$
