Abstract: Shelf-stable, one-package aqueous latices, which are curable with or without the application of heat, consist essentially of an alkaline-curable, self-crosslinking emulsion polymer, selected organic metal salts, and water. The alkali, alkaline earth, or heavy metal salts of C.sub.1 -C.sub.6 organic acids (e.g., sodium acetate) are post-added to th polymer emulsion or present during the polymerization. The polymer typically comprises about 90-99.9% by weight of one or more vinyl polymerizable monomers (e.g., acrylates, vinyl esters, and ethylene) and 0.1-10% by weight of a polymerizable non-ionic or cationic self-crosslinking monomer containing halohydrin groups (e.g., 3-chloro-2-hydroxypropyl (meth)acrylate or the reaction product of epichlorohydrin and N,N-dimethylaminopropyl methacrylamide or methacrylate).

Abstract: High solids, low viscosity, alkaline-curable, thermosetting cationic vinyl ester based polymer latices, characterized by the high molecular weight of the polymer therein, are prepared by polymerizing at least 5% of selected vinyl esters (up to C.sub.6), 0.5-10% of a self-crosslinking cationic quaternary ammonium monomer, and optionally a vinyl polymerizable monomer such as butyl acrylate, ethylene, acrylamide, diallyl maleate, and/or 2-hydroxyethyl acrylate. The polymerization is carried out in the presence of water, a watersoluble cationic azo initiator, a water-soluble amino thiol salt chain transfer agent, and a cationic and/or nonionic surfactant. The latices are useful as formaldehyde-free binders for polyester nonwovens.

Abstract: 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.

Abstract: This invention is directed to a novel water soluble conductive material which is capable of being polymerized by actinic radiation. More specifically, this invention involves the use of a radiation curable quaternary ammonium salt obtained by mixing at least one tertiary amine having acryloyl or methacryloyl unsaturation and at least one halide. When the water-soluble conductive material is subjected to actinic radiation sufficient to cause polymerization, it maintains its conductive character, but becomes essentially impervious to attack by water or solvent, and remains tack-free even at high relative humidity. When the water-soluble conductive material is polymerized by actinic radiation, it is not necessary to drive water off during cure and then rehumidify to obtain proper conductivity as is often necessary with the prior art coatings.

They have an intrinsic viscosity higher than 6 and a measured cationicity higher than 90% of the theoretical cationicity.
