SOLUTION: There is provided the adhesive-carrying porous film for a cell separator, employing, as a base porous film, a porous film wherein the temperature for decreasing a thickness of the porous film to 1/2 of the thickness of the porous film at the room temperature is 200°C or more, and the thickness decrease is measured by means of a needle prove thermomechanical analyzer which is placed on the porous film in both the cases of the measurement. The adhesive-carrying porous film includes also a partially-crosslinked adhesive carried by the base porous film, this adhesive being partially crosslinked by reacting a reactive polymer having a functional group with an isocyanate group with a polyfunctional isocianate. The base porous film is made from a polyolefin resin composition composed of: a polyolefin resin having at least 500 thousands of weight-average molecular weight; and crosslinkable rubber having a double bond in a molecular chain wherein the crosslinkable rubber is crosslinked.

摘要： PROBLEM TO BE SOLVED: To obtain a film having high strengths and a high porosity by kneading under heating a polymer composition containing a polyolefin resin containing an ultrahigh-molecular-weight polyolefin resin and a saturated thermoplastic elastomer and a solvent, molding the mixture into a sheet, rolling and biaxially orienting the sheet, desolventing the oriented sheet, and removing the thermoplastic elastomer from the sheet by extraction. SOLUTION: The paste obtained by heating the polymer composition and a solvent is kneaded at 115-185 deg.C, and the product of kneading is molded into a gel-like sheet under cooling to a temperature equal to or lower than the coagulation point of the solvent to crystallize the ultrahigh-molecular-weight polyolefin resin (of a melting point of M deg.C). Next, the gel-like sheet is rolled at a temperature from (M+5) to (M-30) deg.C, and biaxially oriented at a temperature of (M+5) to (M-30) deg.C, and the obtained oriented film is desolvented to remove part or all of the saturated thermoplastic elastomer by extraction. The saturated thermoplastic elastomer is one consisting of a block selected among ethylene blocks, etc., and a styrene block.
