Abstract: This invention relates to modified aqueous dispersions of water-insoluble latex polymer prepared by swelling an initial water-insoluble latex polymer, prepared by emulsion polymerization, with additional ethylenically unsaturated monomer, including at least one monomer with two or more sites of ethylenic unsaturation, and subsequently polymerizing the additional monomer within the swollen latex particles.

Abstract: A method for improving the quality of a mastic coating system by using a latex barrier tiecoat which is composed of a water-insoluble latex polymer and a multivalent metal ion. The tiecoat is applied to a substrate and then a mastic coating is applied to the tiecoat to yield a mastic coating system having excellent resistance to blistering when the mastic coating system is exposed to long-term ponded water.

Abstract: Modified solution polymer compositions useful for films, coatings, caulks, adhesives, and mastics having advantitious properties such as low surface tack, short drying time, high tensile strength, and hardness, uses of such compositions, and processes for preparing them are disclosed.

Abstract: There are disclosed radiation curable compositions containing (a) about 5-95% by weight of at least one .beta.-cyanoethoxyalkyl acrylate, (b) about 1-90% by weight of a photopolymerizable acrylated polymer or oil, and (c) from 0 to about 5% by weight of a photoinitiator. The compositions are useful in providing 100% solids coatings and adhesive compositions which are capable upon exposure to radiation, and which are useful in a variety of applications such as for coating textiles and fabrics, for producing pressure sensitive adhesives, and for producing laminating adhesives.

Abstract: Monoethylenically unsaturated derivatives of substituted benzophenones or acetophenones which are prepared by reaction of such a benzophenone or acetophenone with a vinyl benzyl halide, such as the chloride, are polymerizable to form homopolymers or copolymers e.g. with a wide variety of conventional ethylenically unsaturated monomers, especially monoethylenically unsaturated vinyl or vinylidene monomers. The resulting polymers are sensitive to radiation, such as ultraviolet light, e.g. having a wave length of 2,000 to 5,000 angstroms, and readily cross-link or cure upon exposure to such radiation. Adhesives, binders, coatings, and impregnating compositions are made from the polymers.

Abstract: Bis-ketimine esters of the general formula ##STR1## wherein, for example, R and R.sup.1 are alkyl groups,X is alkylene, andY is the non-carboxyl moiety of a dicarboxylic acid, are disclosed. Said compound is mixed with an acid polymeric anhydride to form an ambient moisture-curable adhesive composition.
