摘要： A process is disclosed for the formation of a high flux composite membrane having a thin discriminating film affixed to a porous support layer through a glue layer. The process comprises the formation of the discriminating film by irradiating an aqueous polymer solution in the substantial absence of drying and under conditions which are sufficient to form a polymer film on the surface of the polymer solution at the interphase of the solution and a blanketing fluid. The film is then affixed to the support through the glue layer which may be the same polymer solution from which the discriminating film is formed.

摘要： Reverse osmosis membranes treated with polymers bearing carboxylic acid groups and optionally pendant hydroxyl or amide moieties display enhanced salt rejection and/or increased water flux. This treatment is particularly useful for improving the membrane characteristics of cellulose acetate and polyamide membranes.

摘要： An improved composite polyamide membrane and methods of making the membrane are described. This improved membrane is prepared using a cationic polymeric wetting agent in an aqueous solution containing a polyfunctional amine reactant which is interfacially polymerized with an acyl halide to form a thin film polyamide discriminating layer on a microporous support. Alternatively, the wetting agent can be applied directly to the substrate and the interfacial polymerization can occur on said treated substrate. The resulting membrane exhibits an unexpected combination of high water flux, high rejection of divalent anion salts, variable sodium chloride rejection and good caustic resistance at low operating pressures. In one embodiment of this invention, a porous substrate is first treated with an aqueous piperazine solution containing a copolymer of vinylbenzyl dimethyl sulfonium chloride and methacrylic acid and then the coated microporous support is contacted with trimesoyl chloride in an organic solvent.

摘要： A method for preparing a filler composition useful for preparing a nanocomposite polymer is provided. The method includes a first step of dispersing a water dispersible filler material in a liquid comprising water to form a dispersion and a second step of replacing at least a portion of the water of the liquid with an organic solvent. The resulting filler composition features a water concentration of the liquid of less than six percent by weight, and the average size of at least one dimension of the filler material is less than two hundred nanometers upon examination by transmission electron microscopy of a representative freeze dried sample of the dispersion of the first step. A nanocomposite polymer, particularly and epoxy resin composition, can be prepared by mixing the above-made filler composition with one or more polymer, polymer component, monomer or prepolymer.
