ABSTRACT:
This invention provides a crystalline polyolefin-type resin composition comprising a crystalline polyolefin-type resin and two kinds of nucleating agents, i.e., a di(p-substituted-benzylidene)sorbitol (I) and an o-substituted benzylidene-p-substituted benzylidene sorbitol (II) which are used in an amount of about 0.08 to about 1 part by weight per 100 parts by weight of the resin, and the proportion of (II) to (I) is about 0.5 to about 8 parts by weight of (II) per 100 parts by weight of (I). The composition can give molded articles having high transparency and other properties and free from bleeding-out.
