Hydrophilic polymer alloy, fiber and porous membrane comprising this polymer alloy, and methods for preparing them
摘要：
A hydrophilic polymer alloy which has a permanent hydrophilic nature, a sufficient mechanical strength and a high safety and which is suitable for the formation of hydrophilic porous membranes manufacturable by an industrially advantageous process can be prepared by blending an amorphous hydrophilic copolymer (X) containing 10 mole % or more of an ethylene unit, 10 to 60 mole % of a vinyl alcohol unit and 1 mole % or more of a vinyl acetate unit with a polyolefin (Y). Furthermore, this polymer alloy is also suitable for the formation of hydrophilic (porous) fibers having a sufficient mechanical strength and antistatic function.
摘要（中）：

具有永久亲水性，足够的机械强度和高安全性并且适于形成可通过工业上有利的方法制造的亲水性多孔膜的亲水性聚合物合金可以通过将含有10个 摩尔％以上的乙烯单元，10〜60摩尔％的乙烯醇单元和1摩尔％以上的具有聚烯烃（Y）的乙酸乙烯酯单元。 此外，该聚合物合金也适于形成具有足够的机械强度和抗静电功能的亲水（多孔）纤维。
