MIKROPOROST HALFIBERMENBRAN FOR PLASMAFERES, SAMT SETT ATT FRAMSTELLA MEMBRANET |
摘要 |
Microporous hollow fibre membrane (I) of hydrophilic polyetherpolycarbonate block copolymer (II) for use in plasmaphoresis is claimed in which the membrane (I) has a symmetrical wall structure with smoothly rounded pore openings without sharp edges. Also claimed is a process for making (I) by extruding a soln. of (II) in the form of a hollow fibre (III) and then gelling and opt. washing the fibre. - (I) has a pore dia. of 0.008-0.8 pref. 0.5 microns, a porosity of above 65 pref. 80-85% and a thickness of 20-300 pref. 100 micron. (II) comprises bisphenol A/polyalkylene oxide polycondensate of formula (A) where R is CH2CH2 or combinations of CH2-CH=CH and CH=CH pref. CH2CH2, m=40-100, pref. 80, n=10-155 pref. 152 and p=0.5-3 pref. 1. - (I) has a wide cutt off and relatively high filtration rates and the pore openings do not cause hemolysis when used to separate plasma from blood cells.(0/0) |
