Abstract
1317682 Porous coating KINYO-SHA CO Ltd 8 June 1971 [15 June 1970] 19452/71 Heading B2E [Also in Division C3] A coated substrate, e.g. a non-woven nylon is made by making a porous polymer comprising a plurality of interconnected cells, by (a) mixing together a liquid prepolymer which can be converted from liquid to solid form by cross-linking during steps (b), an inert organic liquid which is insoluble in the prepolymer and does not boil under the conditions of step (b), and an emulsifier to form a stable emulsion of dispersed liquid prepolymer in the organic liquid; coating the substrate with the emulsion; (b) applying heat, radiation or light to the emulsion coating in the presence of a cross-linking agent for the prepolymer to coagulate the prepolymer dispersion into larger particles and to solidify these particles and to bond them together to form a porous polymer coating with a plurality of interconnected cells filled with the organic liquid and (c) extracting the organic liquid from the cells.
