TRANSLUCENT POLYPROPYLENE FILM

摘要

PURPOSE:To improve the degree of haze of a film by preparing 0.5-100 pts.wt. of a copolymer composed of polyethylene or ethylene with 50% ethylene content or more and another alpha-olefin and/or radical polymerized polar unsaturated compound. CONSTITUTION:A composition containing (A) 100 pts.wt. of crystal propylene- ethylene block copolymer composed of 0.5-60 wt.% of block polymer section containing 50-100wt.% of ethylene content and a propylene polymerized section containing 80wt.% propylene content or more or 99.5-40 pts.wt. of a copolymerized section composed of propylene and another alpha-olefin, (B) 0.001-1 pts.wt. of an organic peroxide of 10 hours of period of reduction by half and 60 deg.C decomposition temperature or more, and (C) 0.5-100 pts.wt. of a compolymer composed of polyethylene or ethylene containing 50% ethylene content or more and another alpha-olefin of radical polymerized polar unsaturated compound is prepared. A desired film is manufactured by using said composition.
