Abstract
PURPOSE: A packaging film having improved heat-sealing properties, by copolymerizing a specific composition of ethylene, propylene and butene-1 using a Ziegler- Natta catalyst so that a novel three dimensional polymer is formed into a film.
CONSTITUTION: A composition with a ratio of (A) 1.0W3.0wt% ethylene, (B) 67.0W98.0wt% propylene, and (C) 1.0W3.0wt% butene-1 is fed to a polymerization system, and copolymerization is carried out using a Ziegler-Natta catalyst consisting of diethyl aliminum chloride, etc., and titanium trichloride, etc., to give a three-dimensional copolymer. This copolymer is melted and kneaded by an extruder and extruded to filmy state, orientated, to give the desired film.
