亲水微孔膜
摘要：
一种包括热塑性树脂的亲水微孔膜，该亲水微孔膜经过亲水化处理且最大孔径为10-100nm，其中，当含有具有80重量％或以上单体比率的3重量％牛免疫球蛋白在0.3MPa的恒压进行过滤时，从开始过滤计，5分钟内的平均渗透率(升/m2/h)(简称为球蛋白渗透率A)满足下列公式(1)；从开始过滤55分钟后计，5分钟内的平均渗透率(升/m2/h)(简称为球蛋白渗透率B)满足下列公式(2)：球蛋白渗透率A＞0.0015×最大孔径(nm)2.75(1)；球蛋白渗透率B/球蛋白渗透率A＞0.2 (2)。
摘要（英）：

A microporous hydrophilic membrane which comprises a thermoplastic resin, has been hydrophilized, and has a maximum pore diameter of 10 to 100 nm, wherein when a 3 wt.% bovine immunoglobulin at least80 wt.% of which is accounted for by monomers is filtered therethrough at a constant pressure of 0.3 MPa, the average permeation rate (L/m<2>/h) for a period of 5 minutes after filtration initiation (referred to as globulin permeation rate (A)) satisfies the following relationship (1) and the average filtration rate (L/m<2>/h) for a period of 5 minutes after the time when 55 minutes have passed since filtration initiation (referred to as globulin permeation rate (B)) satisfies the following relationship (2). [Globulin permeation rate (A)] > 0.0015 x (maximum pore diameter (nm))<2.75> (1) [Globulin permeation rate (B)]/[globulin permeation rate (A)] > 0.2 (2).
