MICROPOROUS HYDROPHILIC MEMBRANE |
摘要 |
<p>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 least 80 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)</p> |
