Text Solution

Verified by Experts

Nylon 6,6 is a linear polyamide polymer formed by the condensation polymerisation reaction .
It monomers are : (a) Adipic acid : ` HOOC - (CH_(2))_(4)-COOH`
(b ) Hexamethylene diamine : ` H_(2)N - (CH_(2))_(6) - NH_(2)`
When equimolar aqueous solutios of adipic acid and hexmethylene diamine are mixed and heated , there is neutralization to form a nyon salt . During polymerisation at 553 K nylon salt loses a water molecule to form nylon 6,6 polymer.
