ABSTRACT:
High modulus filaments are melt-spun from polyimide-esters derived from 2,6-naphthalene dicarboxylic acid and either a substituted diphenol and 4-(4'-carboxyphthalimido)benzoic acid or terephthalic acid and 4-(4'-hydroxyphthalimido)phenol. The polyimide esters are optically anisotropic in the melt. As-spun filaments from these polymers can be heat treated while free from tension to increase their tenacity.
