| titleOfInvention | Method of producing microporous polyolefin membranes |
| abstract | The present invention relates to a method for producing a microporous polyolefin membrane having a relatively large pore size, high permeability, and suitable for use in water treatment, microfiltration, and the like. The process produces a solution by dissolving the polyolefin composition in a solvent, extruding the solution in the form of a gel sheet through the die lip, then rapidly cooling the gel sheet, removing residual solvent in the cooled sheet with a washing solvent, Drying the resulting sheet to remove the washing solvent. The polyolefin composition is a mixture of an ultrahigh molecular weight polyolefin (A) having a weight average molecular weight of 5 × 10 5 or more and a polyolefin (B) having a weight average molecular weight of less than 5 × 10 5 , wherein the weight ratio of (B) to (A) is 0.2 To 20. |
