Abstract

Polyolefin resin compositions having a sea and island structure wherein cycloolefin resin, graft modified cycloolefin resin and graft modified elastomer components are finely dispersed in polyamide by melt kneading the cycloolefin resin, graft modified cycloolefin resin, graft modified elastomer and polyamide. Molded products formed by using the polyolefin resin compositions of the present invention are high in impact strength and surface characteristics, particularly less in surface delamination, and also excellent in surface glossiness. The molded products are low in water absorption properties and also excellent in oil resistance.
