    Abstract: A membrane of defined pore structure and controlled pore diameter and a method of preparing the membrane which comprises dispersing in a water soluble polymer solution (A) an organic polymer solution (B), the water-soluble polymer solution (A) being a non-solvent for the polymer solution (B), to form micro-spherical droplets of the polymer solution (A) which are enveloped by a solid phase consisting of a coagulated or cross-linked polymer solution (B); evenly casting the dispersion on a flat surface; and evaporating the solvent for the polymer solution (B) to form a microporous membrane comprised of the polymer (B), the porosity, pore size, and void volume of the microporous membrane being a function of the polymer (A) concentration, the microsphere dimensions and the temperature and evaporation rate. The water-soluble polymer (A) is selected from polyethyleneimine, gelatin, polyvinyl-pyrrolidone, polyvinyl pyridinium halide, polyacrylic acid, polyhydroxyethylmethacrylate (HEMA), dextran, or polyvinyl acetate. The continuous phase polymer (B) is selected from a brominated polyphenylene oxide, polyphenylene oxide, polyacetic acid, polystyrene, polyglycol acrylate (PGA), polymethylmethacrylate, cellulose acetate, polyvinyl acetate, polycarbonate and polyvinylidene fluoride.

    Abstract: 1,135,649. Coating compositions. UNITED SHOE MACHINERY CORP. 15 Dec., 1965 [18 Dec., 1964], No. 53160/65. Headings C3C, C3P and C3R. [Also in Division B2] Coating compositions suitable for depositing porous films comprise an aqueous dispersion of a film-forming polymeric material and fine droplets, of which from 30-60% have dimensions in the range of 0À001-0À003 mm. and substantially the remainder of said droplets have dimensions in the range of 0À003-0À010 mm., of a water-immiscible volatile organic liquid in which the polymeric material is insoluble or substantially insoluble, said liquid being suspended in the aqueous phase of said dispersion and being present in an amount of 25-300% based on the weight of said polymeric material. Preferred organic liquids are petroleum hydrocarbon fractions, e.g. mineral spirits, petroleum naphtha and kerosene; others mentioned are halogenated hydrocarbons and nitroparaffins. The polymeric material may be, for example, a latex of a butadiene-acrylonitrile copolymer which may be carboxylated, an acrylic ester polymer or copolymer emulsion, a latex of polyvinyl chloride or copolymer of vinyl chloride with e.g. vinyl acetate, or a latex of an elastomeric polyurethane, formed by reacting a polyester or polyether polyol with excess of a polyisocyanate and then chain extending the -NCO terminated condensate by reaction with a compound such as a polyol, polyamine or amino-alcohol. The composition may include a modifier to improve gel strength of the coatings, e.g. casein rendered water-soluble by treatment with an alkaline material, polyvinyl alcohol, methyl cellulose, and the insoluble resinous residue obtained from the distillation of pine tar resin. Other components which may be added include waxes or wax-like substances, gums, colouring agents, e.g. carbon black or zinc oxide, and mineral fillers. After a coating has been deposited on a surface, it is coalesced by evaporating water whereby the polymer particles gel; and when the solvent droplets are evaporated a porous coating is obtained.
