Nylon 6,6 is obtained by polymerising which pair of monomers?
Ahexamethylenediamine and adipic acid
Bhexamethylenediamine and terephthalic acid
Ccaprolactam alone
Dethylene glycol and adipic acid
Answer: A
Nylon 6,6 has six carbons in the diamine (hexane-1,6-diamine) and six in the diacid (hexanedioic acid, adipic acid). Their step-growth condensation forms amide links with loss of water.
