Abstract

PURPOSE: A specific propylene-1-butene random compolymer is incorporated with an isotactic polypropylene to produce title composition with improved transparency and resistance to whitening caused by impact without any adverse effect on the characteristics of polypropylene.
CONSTITUTION: (A) 95W50wt% of an isotactic polypropylene is blended with (B) 5W50wt% of a propylene-1-butene random copolymer that has a melt index of preferably 0.1W40, the propylene content of 55W85, preferably 60W82mol% and the heat of crystal fusion of 10W80, preferably 20W70Joule/g measured with differentially scanning type calorimeter, under melting.
USE: Vessels for edible oil, vacuum-molding products such as blister packaging tapes, films for packaging, battery cases or book covers
