FORMMASSEN BESTEHEND AUS ALIPHATISCH/AROMATISCHEN COPOLYAMIDEN.

摘要

Moulding compsns. consist of aliphatic-aromatic copolyamides (I) having distributed statistically over the polymer (A) more than 40, but less than 100, mol.% aliphatic amine and/or carboxylic acid residues. (B) less than 60 mol.% aromatic amine and/or carboxylic acid residues, contg. as aromatic diamine 4,4'-bis(4-amino phenoxy)diphenyl sulphone (II), 4,4'-bis(3-amin o phenoxy)diphenyl sulphone, 4,4'-bis(4-amino phenoxy)- benzophenone, 4,4'-bis(3-amino phenoxy) benzophenone, or mixt. thereof. Pref. (I) contains more than 60, partic. 80-95 mol.% (A). (B) is (II).
