| Zusammenfassung: | A microporous membrane is disclosed which is suitable as a membrane filler in liquid permeation, microfiltration and ultra filtration in reverse osmosis, as a porous support substrate or for another reverse osmosis membrane, in electrophoresis, curtain electrophoresis, thin layer, gas or liquid chromatography or as a substrate for enzyme attachment. The membrane consists essentially of a polyester resin of the general formula wherein a is an integer of at least 3 and not greater than 7 and n is an integer greater than about 45. |
