ABSTRACT:
High modulus filaments are melt-spun from polyesters which are derived from 3,4'-dihydroxybenzophenones or 3-hydroxy-4'-(4-hydroxyphenyl-)benzophenone and terephthalic, 2,6-naphthalene dicarboxylic, or bibenzoic acid. The polyesters are optically anisotropic in the melt. As-spun filaments from these polyesters can be heat treated while free from tension to increase their tenacity.
