Abstract

PURPOSE: To provide a titled copolymer capable of forming a film with excellent transparency, anti-block property and heat sealability having propylene units, α- olefin units and ethylene units in a specific range obtained by copolymerizing propylene, α-olefin and ethylene.
CONSTITUTION: (a) Propylene, (b) a straight-chainα-olefin such as pentene-1, hexene-1, heptene-1, octene-1, nonene-1, or decene-1, and (c) ethylene are copolymerized in the presence of a Ziegler type composite catalyst based on a titanium compound and an organo aluminum compound to obtain a titled copoymer having a composition comprising 76W95.5wt%, pref. 88W95.5wt% of 0.5W20wt%, (a) pref. 1W5wt% of (b) component unit and >4W8wt%, pref. >4W7wt% of (c) component unit and this copolymer is molded to a single film, a composite film or the like corresponding to a purpose.
