Blends made of polyarylene ethers and of polyarylene sulfides

Abstract

The present invention relates to thermoplastic molding compositions comprising the following components: (A1) at least one polyarylene ether having an average of at most 0.5 phenolic end groups per polymer chain, (A2) optionally at least one polyarylene ether having an average of at least 1.5 phenolic end groups per polymer chain, (B) at least one polyarylene sulfide, (C) at least one hyperbranched polymer selected from hyperbranched polycarbonates and hyperbranched polyesters, (D) optionally at least one functionalized polyarylene ether comprising carboxy groups, (E) optionally at least one fibrous or particulate filler, and (F) optionally further additives and/or processing aids. The present invention further relates to a process for producing the thermoplastic molding compositions of the invention, to the use of these for producing moldings, fibers, foams, or films, and to the resultant moldings, fibers, foams, and films.
