Abstract

There is provided a polyolefin resin composition for injection molding which comprises adding to polyolefin a condensate of sorbitol with an aldehyde compound and a lubricant of 1/20 to 1/2 parts by weight based on 1.0 part by weight of said condensate. Thereby polyolefin injection moldings with good transparency are obtained without bringing a foaming phenomenon.
