Abstract
Official abstract text for this publication.
Polyolefin compositions suitable for injection moulded items e.g. for impact bumpers and car interiors comprising from 30% to 90% by weight of an heterophasic propylene polymer composition (A); and from 10% to 70% by weight of a multimodal ethylene/C6-C12 alpha olefin copolymer (B); having density from 0.850 to 0.920 g/cm 3 , total comonomer content from 6% to 30% by weight, Mw/Mn from 4 to 20; intrinsic viscosity in decalin at 135° C. from 1.0 to 4.0 dL/g, and comprising an HDPE fraction (HDPE % wt) up to 30% wt; further comprising up to 50% by weight of a filler (C) and optionally, in amount up to 10% by weight with respect to the overall composition, an impact modifier masterbatch component (D) consisting of a ultra-soft heterophasic copolymer component.
First claim
Opening claim text (preview).
What is claimed is: 1. A polyolefin composition comprising: A) from 30% to 90% by weight of a propylene polymer composition comprising: a1) from 20% to 90% by weight of a propylene homopolymer, or a copolymer of propylene or blends thereof containing 8% by weight or less of copolymerized ethylene or C 4 -C 10 α-olefin(s) or blends thereof, said homopolymer or copolymer or blends having an isotactic index greater than 80%, a2) from 10% to 80% by weight of a copolymer of ethylen…
