Question

Seekh · Accepted Answer

The first step in Kevlar’s condensation polymerization is that the monomers react with each other to create dimers, a small pair of linked molecules. After the dimers form, small molecules such as water or ammonia are eliminated from the reaction mixture. These dimers then link together, forming longer chains. As more dimers join, long chain polymers emerge, creating the high‑strength Kevlar fiber. For example, two terephthaldehyde and two p‑phenylenediamine molecules combine, lose water, and repeat this process until a long, rigid polymer chain is built.
