Title:
POLYPROPYLENE RESIN COMPOSITION AND FILM MADE FROM THE SAME
Document Type and Number:
WIPO Patent Application WO/2009/008459
Kind Code:
A1
Abstract:
Disclosed is a polypropylene resin composition obtained by melt-mixing 94-98
parts by weight of a propylene copolymer (A) which is composed of a polymer moiety
having a limiting viscosity of not less than 2.0 (dL/g) and obtained by polymerizing
a monomer mainly composed of propylene and a copolymer moiety obtained by copolymerizing
propylene and ethylene, 2-6 parts by weight of an ethylene polymer (B) having
a density of not less than 0.920 g/cm3 and an organic peroxide (C) (with
the total of the propylene copolymer (A) and the ethylene polymer (B) being 100
parts by weight). This polypropylene resin composition has a melt flow rate
of not less than 1.5 (g/10 min).
