摘要:
The present invention is directed to a first polypropylene composition comprising a propylene copolymer as matrix phase (A) comprising a homo/random/block copolymer consisting of a) a propylene homopolymer (A1); b) a propylene random copolymer (A2); and c) an ethylene-propylene rubber (EPR) (A3) and a polyolefin (B) dispersed in the matrix phase (A), which comprises hydrolysable silicon-containing groups. The present invention is furthermore directed to a second polypropylene composition comprising a matrix phase (A) comprising a propylene homo- or copolymer with an impact strength at +23° C. of at least 40.0 kJ/m2 in a Charpy notched test according to ISO 179-1eA:2000 and a polyolefin (B) dispersed in the matrix phase (A), which comprises hydrolysable silicon-containing groups. The invention is furthermore directed to a production process for the polypropylene compositions and an article made thereof.
