Patent ID: 8802781

Claim:
A polyolefin composition comprising: A) from 30% to 90% by weight of a propylene polymer composition A) comprising: a1) from 20% to 90% of a propylene homopolymer, or a copolymer of propylene containing 3% or less of derived units of ethylene or C 4 -C 10 α-olefin(s) or of combinations thereof, said homopolymer or copolymer having a content of isotactic pentads (mmmm), measured by 13 C NMR on the fraction insoluble in xylene at 25° C., higher than 96%; a2) from 10% to 80%, of a copolymer of ethylene containing from 40% to 70% of derived units of propylene or C 4 -C 10 α-olefin(s) or of combinations thereof, wherein the propylene polymer composition A) has a melt flow rate from 15 to 45 g/10 min; and B) from 10% to 70% by weight of a multimodal ethylene copolymer wherein the comonomer is selected from the derived units of alpha olefins of formula CH 2 ═CHT wherein T is a C 3 -C 10 alkyl group; having the following properties: i) a density (with ISO 1183) from 0.850 to 0.935 g/cm 3 ; ii) a total comonomer content from 6% to 30% by weight; iii) a content of 1-butene derived units from 0 to 2% by weight; iv) a Mw/Mn from 4 to 20; and v) an intrinsic viscosity (decalin at 135° C. as determined according to EN ISO 1628-312003) between 1.0 and 4.0 dL/g, and C) from 0 to 50% by weight of a filler.
