Drawable high tensile strength aramids

Aramids, which in the drawn state have high tensile strengths tensile elongations, and tensile moduli, are made from units derived from selected 2,2'-disubstituted-4,4'-bibenzoic acids, 3,4'-oxydibenzoic acid or 3,4'-dicarboxybenzophenone, p-phenylenediamine, and optionally terep...

Zusammenfassung:	Aramids, which in the drawn state have high tensile strengths tensile elongations, and tensile moduli, are made from units derived from selected 2,2'-disubstituted-4,4'-bibenzoic acids, 3,4'-oxydibenzoic acid or 3,4'-dicarboxybenzophenone, p-phenylenediamine, and optionally terephthalic acid. The aramids are useful for ropes and composites.
