Random propylene copolymer for bottles with good optical properties |
摘要 |
Propylene copolymer having a melt flow rate MFR2 (230° C.) in the range of more than 1.0 to below 2.5 g/10 min, a xylene cold soluble content (XCS) in the range of 25.0 to 35.0 wt.-%, a comonomer content in the range of more than 7.5 to 12.0 wt.-%, wherein further the xylene cold soluble (XCS) fraction of the propylene copolymer has comonomer content in the range of 16.0 to 28.0 wt.-% and an intrinsic viscosity (IV) in the range of more than 1.2 to below 2.5 dl/g. |

1. A propylene copolymer having:
(a) a melt flow rate MFR2 (230° C.) measured according to ISO 1133 in the range of more than 1.0 to below 2.5 g/10 min, (b) a xylene cold soluble content (XCS) determined according to ISO 16152 (25° C.) in the range of 25.0 to 35.0 wt. %, based on the total amount of the propylene copolymer, and (c) a comonomer content in the range of more than 7.5 to 12.0 wt. %, based on the total amount of the propylene copolymer, wherein further; (d) the comonomer content of xylene cold soluble (XCS) fraction of the propylene copolymer is in the range of 16.0 to 28.0 wt. %, based on the total weight of the xylene cold soluble (XCS) fraction, and (e) the intrinsic viscosity (IV) determined according to DIN ISO 1628/1 (in decalin at 135° C.) of the xylene cold soluble (XCS) fraction of the propylene copolymer is in the range of more than 1.2 to below 2.5 dl/g. |
