ABSTRACT:
An aramid composition consisting essentially of repeat units derived from p-phenylenediamine, terephthalic acid, 3,3'-bibenzoic acid, and optionally chloroterephthalic acid, is disclosed. The aramids are especially useful for fibers, which after drawing usually have enhanced tensile moduli and strengths, which makes them especially useful in ropes and cables, and in composites.
