.... The polymer poly-p-benzamide was found to form liquid crystalline solutions due to the repetitiveness of its molecular backbone. The key for the structural requirement for the backbone is para orientation on the benzene ring, which allowed for rod-like molecular structures. This technology was used when Du Pont released aramid fiber in 1971. What is it? Kevlar is an aramid, a term invented as an abbreviation for aromatic polyamide. The chemical composition of Kevlar is poly para-phenyleneterephthalamid ....
