| titleOfInvention | Porous film and method for producing the same |
| abstract | (57) [Problem] To provide a porous film which does not easily undergo heat shrinkage, has excellent low-temperature shutdown characteristics and high porosity, and a method for producing the same. A high molecular weight polyolefin having a weight average molecular weight of 1 × 10 6 or more and another resin having a melting point or softening point at a temperature equal to or lower than the melting point of the high molecular weight polyolefin, a shutdown temperature of 135 ° C. or lower, Porosity of 4 A porous film having a heat shrinkage of 0% or more and 30% or less, and a weight average molecular weight of 1 × 1 0 6 or more high molecular weight polyolefin, shaping the melting point or resin composition having a softening point contain other resins and solvents is a temperature lower than the melting point of the high molecular weight polyolefin kneaded into a sheet-like, stretching and desolvation process And then heat impregnating the high-molecular-weight polyolefin with a poor solvent having a melting point of −15 ° C. or more and a melting point of + 5 ° C. or less. |
