Abstract

A thermoplastic molding composition, comprising(A) from 20 to 99% by weight of at least one graft copolymer,(B) from 1 to 80% by weight of a copolymer of at least one alpha-olefin and from at least one polar comonomer, with the proviso that the monomers used are not vinyl acetate or any vinylaromatic monomer, and(C) from 0 to 80% by weight of a thermoplastic polymer, prepared by polymerizing a monomer mixture, comprising(c1) from 50 to 100% by weight of at least one vinylaromatic monomer and/or of a C1-C8-alkyl (meth)acrylate, and(c2) from 0 to 50% by weight of at least one monofunctional comonomer, and(D) from 0.1 to 20% by weight of a substantially uncrosslinked, low-molecular-weight polyalkyl acrylate.
