The present invention relates to a heterophasic polypropylene composition comprising - a polypropylene homo- or copolymer (A) as matrix phase, - a polyolefin (B) comprising hydrolysable silane groups dispersed in the matrix phase, and - an acidic silanol condensation catalyst (C),
wherein the polypropylene homo- or copolymer (A) further comprises a particulate acid scavenger, a method for the preparation thereof, and its use in different applications.
摘要:
The invention relates to propylene polymer compositions comprising 50 - 70 wt% of a propylene homo- or copolymer, 5-20 wt% of a first elastomeric ethylene-propylene copolymer, 5-25 wt% of a second elastomeric ethylene-propylene copolymer and 5 - 30 wt% of an ethylene polymer. The propylene polymer compositions are suitable for moulding and they have low haze and a good impact strength/stiffness balance with good impact strengths at low temperatures.
