Abstract

1424057 Reverse osmosis DOW CHEMICAL CO 30 Aug 1973 [31 Aug 1972] 40961/73 Heading B1X A permselective membrane assembly comprises a multiplicity of continuously hollow fibre segments the ends of which segments terminate in the face of at least one resinous tube sheet comprising the non-catalysed reaction product of an isocyanate terminated prepolymer with castor oil or a derivative thereof having a higher functionality. The assemblies are suitable for reverse osmosis.
