Nylon threads are made up of (A) Polyamide polymer (B) Polyethylene polymer (C) Polyvinyl polymer (D) Polyester polymer

Answer : To begin, learn about the components that combine to make nylon fibres. Nylon monomers are held together by bonds that are chemically identical to peptide bonds.

i) Nylon is formed through the reaction of several units of hexamethylene diamine (NH₂(CH₂)₆NH₂) with adipic acid (COOH(CH₂)₄COOH).

ii) Nylon is indeed a man-made material. Its components and preparation technique are wholly artificial biological nature, meaning they have no natural equivalents.

iii) Water is removed from nylon during the condensation-polymerization reaction, which occurs just at bond among its constituent molecules. As a result, it’s a condensation polymer. The following is the reaction:

nNH₂(CH₂)₆NH₂ + nCOOH(CH₂)₄COOH → [−NH(CH₂)₆NHCO(CH₂)₄CO−]_n + nH₂O

As a result, (A) Polyamide polymer is the correct solution to the question.
