Abstract

Thermoplastic molding compositions comprising(A) 5 to 98%-wt., based on components (A) through (E), of at least one elastomeric graft copolymer,(B) 1 to 90%-wt., based on components (A) through (E), of a further copolymer,(C) 1 to 70%-wt., based on components (A) though (D), of an elastomeric block copolymer composed ofat least one block CA (hard phase) having copolymerized units of a vinylaromatic monomer, andat least one elastomeric block C(B/A) (soft phase) having copolymerized units of a vinylaromatic monomer, and of a diene,(D) 0 to 300%-wt., based on components (A) through (C), of a polycarbonate, and(E) 0 to 30%-wt., based on components (A) through (E), of conventional additives and processing aids,are useful for producing films, moldings or fibers.
