Polyamides are polymers where the repeating units are held together by amide links. An amide group has the formula - CONH 2. An amide link has this structure: In an amide itself, of course, the bond on the right is attached to a hydrogen atom. WebDescription. Terephthaloyl chloride acts as a monomer with p-phenylenediamine used in the preparation of polymer viz. poly paraphenylene terephthalamide. It is an active component in performance polymers and aramid fibers, which gives flame resistance, chemical resistance, temperature stability, light weight, and very high strength. shanice benstead
