ABSTRACT:
Fibers made from a blend of poly-p-phenylene terephthalamide (PPDT) and a copolyamide derived from p-phenylene diamine, terephthalic acid and a naphthalenic difunctional monomer show improved properties, particularly tenacity, compared with PPDT fibers. The blend can be processed in the same manner as the PPDT polymer.
