Patent ID: 8309659

Claim:
Filled polyolefin compositions comprising: A) from 20% to 80% by weight of a polypropylene component; B) from 20% to 80% by weight of a filler; wherein the percentages of A) and B) are referred to the sum of A) and B), and A) is selected from the following compositions: a) a polypropylene composition comprising from 20% to 80% by weight of a polypropylene fraction A I ) having a Melt Flow Rate (MFR I ) value of 500 g/10 min. or more, and from 20% to 80% by weight of a polypropylene fraction A II ) having a Melt Flow Rate (MFR II ) value of from 0.1 to 30 g/10 min., the weight percentages of A I ) and A II ) being referred to as the sum of A I ) and A II ); or b) a polypropylene composition comprising from 15% to 72% by weight of a polypropylene fraction A I ) having a Melt Flow Rate (MFR I ) value of 500 g/10 min. or more, from 15% to 70% by weight of a polypropylene fraction A II ) having a Melt Flow Rate (MFR II ) value of from 0.1 to 30 g/10 min. and from 0.5% to 15% by weight of a compatibilizer Q), the weight percentages of A I ), A II ) and Q) being referred to as the sum of A I ), A II ) and Q); said fractions A I ) and A II ) being independently selected from propylene homopolymers and random copolymers of propylene comprising up to 5% by mole of ethylene and/or C 4 -C 10 α-olefin(s), all the Melt Flow Rate values being measured according to ISO 1133 with a load of 2.16 kg at 230° C., wherein the propylene homopolymers and copolymers of the polypropylene fraction A II ) have a molecular weight distribution of higher than 10, in terms of Mw/Mn ratio.
