Abstract

PURPOSE: To manufacture a filter membrane of excellent precision which can be utilized as a microfilter or an ultrafiltration membrane, by making membrane of polymeric polyolefin having specific limiting viscosity from its soln. which is at a specific temp. and is made by dissolving it in a cyclic or halogenated cyclic hydrocarbon of b.p. of 110°C or higher.
CONSTITUTION: A polymeric polyolefin (example; PE) of limiting viscosity 1.5 or higher, measured in decalin at 135°C, is dissolved in cyclic or halogenated cyclic hydrocarbon of b.p. of 111° or higher, pref. 135W240°C. The concn. of the polymeric polyolefin of the soln. is 0.1W100 g/l., pref. 5W40 g/l. The soln. is flow- casted on a support of flat surface, e.g., glass etc., at 80°C or higher, pref. 130W 160°C in order to manufacture a membrane. The resulting membrane is immersed in a coagulating bath of lower alcohol etc. to form an objective filter membrane. The membrane is 30W150μ in thickness
