Polyolefin Resin Composition and Molded Article Produced Therefrom

Abstract

A polyolefin resin composition of the present invention comprises: about 100 parts by weight of a base material including about 60 wt % to about 98 wt % of a polypropylene copolymer resin, and about 1 wt % to about 30 wt % of a polyethylene resin, and about 1 wt % to about 30 wt % of a polyolefin-based elastomer; and about 3 parts by weight to about 15 parts by weight of a maleic anhydride-modified polypropylene resin including about 50 wt % to about 95 wt % of a first maleic anhydride-modified polypropylene having a weight average molecular weight of about 40,000 g/mol or more and a maleic anhydride modification ratio of about 1.5 wt % or more, and about 5 wt % to about 50 wt % of a second maleic anhydride-modified polypropylene having a weight average molecular weight of less than about 40,000 g/mol and a maleic anhydride modification ratio of about 1.5 wt % or more. The polyolefin resin composition has excellent adhesive strength in terms of adhering to a polar substrate, electrolyte resistance, and the like.
