Extrusion blow molded bottles

摘要

Extrusion blow molded bottle comprising a propylene copolymer having a melt flow rate MFR2 (230° C.) of 2.0 to 6.0 g/10 min, a xylene cold soluble content of 20.0 to 40.0 wt.-%, and a comonomer content of more than 4.5 to 12.0 wt.-%, wherein the comonomer content of xylene cold soluble fraction of the extrusion blow molded article is of 16.0 to 28.0 wt.-%.

1. Extrusion blow molded article comprising at least 90 wt. % of a propylene copolymer based on the total amount of the extrusion blow molded article, wherein the propylene copolymer (PC) has:
(a) a melt flow rate MFR2 (230° C.) measured according to ISO 1133 in the range of 2.0 to 6.0 g/10min; (b) a xylene cold soluble content (XCS) determined according ISO 16152 (25° C.) in the range of 20.0 to 40.0 wt. %; (c) a comonomer content in the range of more than 4.5 to 12.0 wt. %; and (d) fulfills inequation (II):co⁡(total)XCS≤0.35(II) wherein, Co (total) is the comonomer content [wt. %] of the propylene copolymer (PC), XCS is the content of the xylene cold soluble fraction (XCS) [wt. %] of the propylene copolymer (PC); wherein further; (e) the comonomer content of xylene cold soluble (XCS) fraction of the propylene copolymer (PC) is in the range of 12.0 to 28.0 wt. %.
