Abstract: A process for adhering high nitrile resins onto a plastic material. The process comprises the steps of selecting a high nitrile resin having a nitrile content of at least about 60 percent by weight and prepared by the copolymerization of an olefinically unsaturated monovinyl nitrile and a monovinyl monomer copolymerizable therewith in the presence of a conjugated diene rubber, preparing a solution comprising from about one to 70 percent by weight of the high nitrile resin in a photopolymerizable solvent comprising from about 30 to 99 percent by weight of the solution and from about 0.

Abstract: Liquid, photocurable coating compositions containing nitrile copolymers. Such compositions comprises from about 10 percent to about 60 percent by weight of a high nitrile copolymer, containing at least about 70 percent by weight of a nitrile polymer; from about 30 percent to 90 percent by weight of a photopolymerizable solvent for the high nitrile copolymer, wherein the photopolymerizable solvent is selected from the group consisting of N-vinyl pyrrolidone, cyanoethylacrylate, styrene, N,N-dimethylacylamide, N,N-methylenebisacrylamide, gamma-butyrolactone and combinations thereof, and from about 0.1 percent to about 10 percent by weight of a photoinitiator soluble in the photopolymerizable solvent for curing the high nitrile copolymer with the incorporation of at least 50 percent by weight of the solvent therein upon exposure to ultraviolet radiation, having a wavelength of from about 2000 .ANG. to 14,000 .ANG.

Abstract: Substrates such as metal and plastic can be protected from the environment by employing a high nitrile polymer coating.

Abstract: Alpha-hydroxy carboxylic acids, such as lactic acid and mandelic acid, are photochemically converted to form high yields of the corresponding alcohol by irradiating a solution containing the alpha-hydroxy carboxylic acid in contact with the semiconductor catalyst material. The semiconductor catalyst material is preferably a metal titanium oxide. The photochemical reaction may be carried out over a wide range of temperatures and pressures and in an oxidative or inert atmosphere.

Abstract: A process is provided for the selective photochemical decarboxylation of alpha-hydroxy carboxylic acids to the corresponding alcohols. The process is enhanced with the use of photo-initiator compounds.

Abstract: A process is provided for the photochemical decarboxylation of a metal salt of an alpha-hydroxy carboxylic acid to form the corresponding alcohol wherein the alpha-hydroxy carboxylic acid metal salt is exposed to light in the absence of a photosensitizing agent.
