    摘要: An absorbent article having, as a back sheet, a porous sheet obtainable by preparing, by melt blending, a melt blended solution comprising 30 to 90 parts by weight of a crystalline polyolefin and 10 to 70 parts by weight of a compound with which the crystalline polyolefin is miscible and in which the crystalline polyolefin will dissolve at or above the melting point of the crystalline polyolefin but which will phase separate below the melting point of the crystalline polyolefin, molding the blended solution into a sheet, and stretching the sheet in at least one direction. The crystalline polyolefin is a polypropylene having a weight average molecular weight (Mw) to number average molecular weight (Mn) ratio (Mw/Mn) of no more than 6.0.

    摘要: A shape memory rubber molded article (1) obtained from a mixture containing a rubber and a crystalline non-polymeric compound. The rubber in the molded article is crosslinked. A deformed state of the shape memory rubber molded article (1) is fixed by crystallizing the non-polymeric compound, and the fixed deformed state is released by melting the non-polymeric compound. The non-polymeric compound is preferably a wax. The shape memory rubber molded article (1) preferably contains a crosslinking agent. In the molded article (1), the rubber and the non-polymeric compound are preferably in finely divided separate phases.
