    摘要： Disclosed are a process for producing a porous stretched article of .beta.-crystalline polypropylene-based resin, the process comprising the steps of crystallizing a melt of a polypropylene-based resin composition at a temperature of 15.degree. to 140.degree. C. to form a solidified product containing .beta.-form crystals and stretching the resulting solidified product at a temprature which is higher than 20.degree. C. but lower than the melting point of the .beta.-form crystals in said solidified product, the polypropylene-based resin composition comprising a polypropylene-based resin and 0.0001 to 5 parts by weight, per 100 parts by weight of the polypropylene-based resin, of at least one specific amide compound; and a porous stretched article produced by the process.

    摘要： 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.
