Question

Which of the following are polyamide polymers?

• A. Nylon - $6,10$
• B. Nylon - $6,6$
• C. Nylon -$5$
• D. Perlon-U

Answer 1

Answer: (A), (B), (C)

Nylon - $6,6$
Nylon - $6,10$
Nylon -$5$

A polyamide is a macromolecule with repeating units linked by amide bonds. Artificially made polyamides can be made through step-growth polymerization or solid-phase synthesis, yielding materials such as nylons, aramids, and sodium polyaspartate.

Nylon - $6,10$ is prepared from monomers of sebacyl chloride and $1,6$-hexanediamine.

Nylon - $6,6$ is synthesized by polycondensation of hexamethylenediamine and adipic acid.

Nylon - $5$ is also a polyamide polymer from the same category having peptide linkage.

Perlon-U, also called polyurethane is a polymer of carbamate (urethane) and not amide.
