Is Kevlar A Polymer?

Hint: We know that a polymer is a huge particle or a macromolecule which basically is a blend of numerous subunits. The term polymer in Greek signifies 'numerous parts'. Polymers can be discovered surrounding us. Various polymers have various exceptional physical and substance properties because of which they discover use in regular daily existence.

Complete answer:
We have to know that the Kevlar is a polymer; this implies that it is composed of an enormous number of a similar fundamental unit, called a monomer, which are joined to one another to shape a long chain. The monomer for this situation consists of an amide group and a phenyl group.
Kevlar is a polyamide, a kind of engineered polymer, where the amide groups are isolated by para phenylene group, implying that the amide groups are connected to one another on inverse sides of the phenyl group (for example carbons 1 and 4).
We can prepare Kevlar by copolymerization of monomers namely benzene-1,4-diamine and terephthaloyl dichloride. We can derive terephthaloyl dichloride from terephthalic acid. This polymerization takes place by nucleophilic carbonyl substitution mechanism. The strength of Kevlar is because of hydrogen bonding among the chains of polymers.
Yes, Kevlar is a polymer that is formed by copolymerization of benzene-1,4-diamine and terephthaloyl dichloride.

Note:
We can use Kevlar in bicycle tires, racing sails, bulletproof vests because of the high tensile strength to weight ratio. The polymerization of Kevlar is a condensation reaction of benzene-1,4-diamine and terephthaloyl dichloride and the side product obtained is hydrochloric acid. We can use Kevlar in the preparation of sleeves, gloves, jackets, and chaps.
