    摘要： A method for filtering liquid or gaseous materials where the filtration is conducted with a porous filter media prepared from an aqueous wet-laid, lofted fiber-reinforced composite sheet, the composite sheet comprising a heat fusible polymer, reinforcing fibers and a binder. The random fiber composite sheet can be selectively lofted or recompressed to form filter media having variable porosity. Also, a membrane support means prepared by applying or treating the fiber-reinforced composite sheet with a discriminating membrane layer.

    摘要： A scrap-free, substantially solid phase, relatively low temperature economical process for rapidly making plastic articles from resinous powders wherein the resultant articles can comprise various polymers including oriented polymers; polymers with a high practical heat distortion temperature; expanded polymers; ultra high molecular weight polymers; blended structures of two or more materials; or multilayered structures. The resinous powders are initially compressed into briquettes, which briquettes are heated to a temperature in the range from about the alpha transition temperature to less than the melting point or melt temperature of the polymer therein to both somewhat soften and sinter the briquettes. The sintered briquettes are forged under conditions which permit substantial plug flow deformation into preforms whereby fusion of the sintered resin powder particles occurs. The resulting preforms can then be cooled for later thermoforming or can be directly transferred to thermoforming molds for forming into desired shaped articles. It is also possible to form at least shallow cans, lids or other items directly in the forging step.

    摘要： Structured particle latexes are prepared by emulsion polymerizing monomeric materials in aqueous media in one or more stages wherein in at least one of the stages a reactive polymeric surfactant is used. The resulting latex contains nonionic particles to which are bound the reactive polymeric surfactant which forms a layer containing stabilizing "ionic" groups such as sulfonium groups, quaternary ammonium groups or sulfonate groups chemically bound at or near the surface of the polymer particles, which are dispersed in aqueous media. The cationic latexes are particularly suitable for beater additives and organic pigments.
