A graft copolymer - composition with an increased notched impact strength, the polypropylene with a broad molecular weight distribution contains

摘要

Disclosed are impact modified graft copolymer compositions comprising (A) from 10 to 90% of a graft copolymer of a propylene polymer material having graft polymerized thereto one or more vinyl monomer(s), (B) from 90 to 10% of at least one broad molecular weight distribution propylene polymer material, and (C) from 2 to 40% of at least one rubber component, wherein (A)+(B)+(C) is 100%, and filled compositions thereof. The compositions are useful as stand-alone structural materials.
