摘要： Novel polymers having high activity as cationic surface-active agents are prepared by the addition polymerization of ethylenically unsaturated aromatic sulfonium salts, e.g., ##STR1## When such polymers are heated and/or dried, they are irreversibly converted to inert, nonionic residues without the elimination of odorous by-products. The novel sulfonium salt polymers having relatively low molecular weight and low charge density are particularly useful as surfactants or emulsifiers in the emulsion polymerization of ethylenically unsaturated monomers such as styrene, butadiene, alkyl acrylates and the like. The polymers having high molecular weight and high charge density are useful as thickeners and flocculants.

摘要： The present invention relates to a quick set composition and a method for preparing the composition. The composition comprises an aqueous sol of a polymer having a backbone that contains pendant cationic groups and pendant acid groups. The sol is prepared by forming a solution of a polymer that contains pendant cationic groups and pendant acid groups in an aqueous-based solvent that contains water and a suitable organic solvent and removing a sufficient amount of the organic solvent from the solution to form a composition characterized by being reversibly dissolvable and reconstitutable by addition and removal of a suitable organic solvent. The composition of the present invention provides quick-set films that can be prepared in the absence additional surface active agents and with a substantial absence of organic solvents.

摘要： A composition comprising an aqueous-based solvent and a water-soluble or water-dispersible polymer that is characterized by having a backbone with at least one pendant weak acid group and at least one pendant strong cationic group associated with a bicarbonate counterion is described. A water-resistant, fast dry-to-the-touch coating that does not release noxious gases can be prepared by applying the composition to a substrate. The coating can be designed to be either permanent, or removable by the addition of mild acids such as aqueous solutions of vinegar or citric acid.

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.
