Question

give synthesis of kevlar??​

Answer 1

Kevlar is synthesized in solution from the monomers 1,4-phenylene-diamine (para-phenylenediamine) and terephthaloyl chloride in a condensation reaction yielding hydrochloric acid as a byproduct. The result has liquid-crystalline behavior, and mechanical drawing orients the polymer chains in the fiber's direction.

Answer 2

Answer:

Kevlar is made through a dehydration reaction between terephthalic acid (one of the two reactants in the synthesis of Dacron®) and p-phenylenediamine. Like with the dehydration reactions to form both polyethelyne terephthalate and Nylon 6-6, this reaction is repeated to form a long chain of the Kevlar molecule.
