Reinforced thermoplastic polyolefin compositions

摘要

Reinforced thermoplastic polyolefin compositions comprising: (A) from 30% to 98% by weight of a polyolefin selected from homopolymers of ethylene and/or copolymers of ethylene with at least another alpha -olefin containing from 3 to 10 carbon atoms, and respectively; (B) from 70% to 2% by weight of a mineral filler; (C) from 0.1 to 10 parts by weight with respect to 100 parts of (A) + (B) of an unsaturated ester having general formula (I): R1-OCO-Z-COOR2 wherein: R1 and R2, the same or different, represent one of the following groups having general formula (II) or (III): HOCH2CH2-ÄOCH2CH2Ün - wherein n is an integer or fraction between 0 and 2, extremes included; R3-ÄOCO-Z-COO-CH2CH2Üm - wherein R3 represents a group having general formula (II) or a hydrogen atom; Z represents a -CH=CH- group and m is an integer or fraction between 0 and 10, extremes included. m
