Title:

POLYOLEFIN RESIN COMPOSITION AND APPLICATIONS THEREOF

Document Type and Number:

WIPO Patent Application WO/2013/031795

Kind Code:

A1

Abstract:

Provided are: a polyolefin resin composition with excellent mechanical properties and heat resistance; a film with few fisheyes which has excellent mechanical properties and heat resistance, and a microporous membrane, which in addition to the abovementioned properties, has excellent permeability and shutdown properties, said film and microporous membrane being obtained from said polyolefin resin composition; and applications thereof. The abovementioned are achieved by means of a polyolefin resin composition obtained by combining, at a specific ratio, an ultra-high molecular weight ethylene polymer (A), a 4-methyl-1-pentene polymer or a 3-methyl-1-pentene polymer (B), and an olefin polymer (C) with two to twelve carbon atoms.
