PERMSELECTIVE MEMBRANES AND METHODS FOR THEIR PRODUCTION |
摘要 |
Disclosed is a membrane material comprising a hydrophobic polymer and a hydrophilic polymer. The hydrophilic polymer consists of 10-50 wt. % of a low molecular weight component having a molecular weight of less than 100,000 and 90-50 wt. % of a high molecular weight component having a molecular weight of at least 100,000. The membrane material may be subjected to an insolubilization treatment to provide a permselective membrane suitable for use in dialysis. The membrane material may have an overall mass transfer coefficient (Ko), for a Stokes' radius of at least 30 .ANG. (as determined by a diffusion test using dextran), of at least 0.0025 cm/min and a permeability to albumin of at most 4 %.
