ABSTRACT:
Novel thin film composite membranes are disclosed. They are prepared from vinyl and related monomers by phase transfer catalysis at the interface between one phase containing a polymerizable vinyl or related monomer and a second phase containing an entity necessary to initiate polymerization of the monomer. The two phases are substantially insoluble in each other. At least one of the phases is a fluid. One of the phases is integral with a porous support or substrate or a precursor of such support or substrate such as a porous organic or inorganic diaphragm made by thermal phase inversion from which the soluble phase has not been extracted.
