Abstract

PURPOSE: To obtain the titled composition for the preparation of translucent film having a high haze value independent of the molding conditions and an easily controllable melt index, by combining a specific propylene-ethylene block copolymer with an organic peroxide.
CONSTITUTION: A composition composed of (A) 100pts.wt. of a crystalline propylene-ethylene block copolymer having 50W100wt% ethylene content and (B) 0.001W1, pref. 0.01W2pts.wt. of an organic peroxide having a decomposition temperature of about ≥60°C corresponding to the half-life of 10 hours, e.g. lauroyl peroxide. Addition of 2W30pts.wt.of polyethylene e.g. high density polyethylene or a copolymer of ethylene and an α-olefin and/or a radically copolymerizable polar unsaturated compound to 100pts.wt. of the compound (A) further improves the haze and the film-forming characteristics.
