| titleOfInvention | Low stress whitening polypropylene composition |
| abstract | The present invention relates to a heterophasic polyolefin composition and articles produced therefrom with improved mechanical and optical properties, particularly low stress whitening. The present invention further relates to a process for the preparation of such a heterophasic polyolefin composition, articles made therefrom, particularly films, and uses of the heterophasic polyolefin composition. The heterophasic propylene copolymer composition comprises a heterophasic propylene copolymer (HECO) comprising a matrix (M) being a propylene homopolymer (H-PP) and an elastomeric propylene copolymer (EPC) dispersed in said matrix (M), wherein the heterophasic propylene copolymer (HECO) has (a) a melt flow rate MFf3/4 (2.16 kg, 230° C.) measured according to ISO 1133 in the range of 5.0 to 25.0 g/10 min, (b) a soluble fraction content (SF) determined by TREF fractionation on CRYSTEX QC, Polymer Char (Valencia, Spain) in the range of 10.0 to 25.0 wt. %, (c) an ethylene content of the soluble fraction content (SF) in the range of from 18 wt. % to less than 39 wt. %, (d) an intrinsic viscosity (IV) determined according to DIN ISO 1628/1 (in decalin at 135° C.) of the soluble fraction (SF) in the range of from 1.5 to 2.5 dl/g, (e) a crystalline fraction content (CF) determined by TREF fractionation on CRYSTEX QC, Polymer Char (Valencia, Spain) in the range of 75 to 90 wt. %, (f) an ethylene content of the crystalline fraction content (CF) of from 0.1 wt. % to 5.0 wt. %, and the heterophasic propylene copolymer composition has a total ethylene content in the range of from 7 to 30 wt. %, determined by quantitative NMR spectroscopy. |
