HYDROPHILIC POLYMER ALLOY, FIBER AND POROUS FILM PRODUCED THEREFROM, AND PRODUCTION OF THE SAME

摘要

A hydrophilic polymer alloy which has a permanent hydrophilicity, sufficient mechanical strengths and a high safety and is suitable for producing a hydrophilic porous film which can be produced by an industrially advantageous method is obtained by blending an amorphous hydrophilic copolymer (X) comprising at least 10 mole % of ethylene units, 10 to 60 mole % of vinyl alcohol units and at least 1 mole % of vinyl acetate units and a polyolefin (Y). This alloy is suitable also for producing a hydrophilic (porous) fiber with sufficient mechanical strengths and an antistatic function.
