A process for preparing solid polymer blends and composites of controlled porosity in microemulsions containing both hydrophilic and hydrophobic phases. The microemulsions are prepared with surfactant systems that may include a cosolvent as a part thereof, together with a hydrophilic monomer, or monomers, dissolved in the hydrophilic phase of the microemulsion, and a hydrophobic monomer, or monomers, dissolved in the hydrophobic phase. Polymerization of the monomers thus present is carried out to provide highly uniform dispersions of the resulting polymers in each other. The invention allows for the control of the morphology of the blends, the improvement in compatability of otherwise incompatible polymers, and improvements in the processability of the polymers due to enhanced thermal and mechanical properties.

A process for preparing porous solid blends and composites of polymers containing at least two solid phases from microemulsions comprising the steps of: (1) forming a reaction mixture by combining components consisting of: water at least one emulsifier soluble in another component of said reaction mixture selected from the group consisting of alkyl benzene sulfonates, alcohol sulfates, fatty amide ether sulfates, alpha-olefin sulfates, paraffin alkane sulfonates, sulfonated fatty acids and esters, sulfosuccinates, phosphate esters, ligno-sulfonates, alkyl phenol ethoxylates, fatty alcohol ethoxylates, ethylene oxide-propylene oxide copolymers, fatty amine ethoxylates, fatty acid ethoxylates, alkanolamides, alkanol ethoxylates, sorbitan esters, primary alkylamines, quaternary ammonium salts, imidazolinium salts and betaines; at least one hydrophilic monomer soluble in water selected from the group consisting of acrylamide, methacrylic acid, acrylonitrile, vinyl methyl ether, N-vinyl pyrrolidone, 4-vinyl pyridine,3-methacrylamidopropyldimethylamine and N,N′-dimethylaminoethylmethacrylate; and at least one liquid hydrophobic monomer selected from the group consisting of styrene, divinylbenzene, vinyl toluene, methyl acrylate, methyl methacrylate, ethyl acrylate benzyl acrylate, benzyl methacrylate, butyl acrylate, vinyl acetate, vinyl chloride, n-vinyl carbazole and ethyl vinyl ether; (2) agitating said mixture until the formation of a microemulsion has been achieved, and (3) polymerizing said hydrophilic and hydrophobic monomers to produce water-insoluble, homopolymer-containing, porous solid blends and composites of polymers.
