ABSTRACT:
The invention relates to high molecular weight, substantially linear copolyarylene sulfides predominantly containing biphenylene sulfide units, which are produced by reaction of aromatic halogen compounds and halobiphenylenes with sulfur donors in dipolar aprotic solvents, and to their use for moldings, films and fibers exposed to high temperatures and--preferably in reinforced form--as injection molding compounds.
