Abstract: N--OR.sub.1 substituted hindered amine light stabilizers impart outstanding stabilization properties to ambient cured coatings based on a variety of resins, the stabilized coatings exhibiting improved durability, weatherability, and the like.

Abstract: N-OR.sub.1 substituted hindered amine light stabilizers impart outstanding stabilization properties to acid catalyzed thermoset coating compositions providing enhanced resistance against the deleterious effects of light, moisture or oxygen without inhibition of cure.

Abstract: N-hydroxy substituted hindered amine light stabilizers impart outstanding stabilization properties to acid catalyzed thermoset coating compositions with enhanced resistance against the deleterious effects of light, moisture or oxygen in the substantial absence of cure inhibition.

Abstract: N-hydroxy-substituted hindered amine light stabilizers impart outstanding stabilization properties to ambient cured coatings based on a variety of resins, the stabilized coatings exhibiting improved durability, weatherability, and the like.

Abstract: Acid-curable thermoset enamel compositions coming in contact with copper or copper-containing alloys are discolored and degrade more rapidly due to leaching of copper into the compositions. The presence of small amounts of benzotriazole or tolutriazole effectively prevents the discoloration and concomitantly retards degradation.

Abstract: Hydroxylamines derived from hindered amines are effective in stabilizing polyolefin compositions containing a stabilizer or mixture of stabilizers selected from the group consisting of the phenolic antioxidants, the hindered amine light stabilizers, the alkylated hydroxybenzoate light stabilizers, the ultraviolet light absorbers, the organic phosphorus compounds, the alkaline metal salts of fatty acids and the thiosynergists, against degradation upon high temperature extrusion, exposure to the combustion products of natural gas, gamma irradiation or upon storage for extended periods.

Abstract: Polyacrylate-containing elastomers, having improved tensile strength and hardness upon vulcanization, comprise blends containing about 35 to 65 percent, by weight, of a sulfur-vulcanizable graft elastomer having a major proportion of ethyl acrylate and a minor proportion of an ethylenically unsaturated comonomer which contains a cure-site for sulfur vulcanization, grafted onto an ethylene-vinyl acetate copolymer, and about 65 to 35 percent, by weight, of a sulfur-vulcanizable polyacrylate elastomer.

Abstract: The present invention relates in general to vulcanizable elastomers of thiodiethanol and, in particular, to the provision of a novel vulcanization system for vulcanizable elastomers of thiodiethanol, comprising sulfur and certain pyrazine compounds.

Abstract: The present invention relates in general to sulfur-vulcanizable elastomers derived from thiodiethanol and, in particular to the provision of a novel vulcanization system therefor comprising sulfur and an aliphatic linear, branched chain of cyclic polyethyleneamine or a dissociable organic salt thereof.

Abstract: A vulcanizable polyacrylate elastomer composition having improved resistance to hydrocarbon oils is provided which comprises one or more lower alkyl acrylic acid ester monomers polymerized with a comonomer containing either a halogen or an epoxy group, in the presence of from about 0.25 to 10 percent, by weight of total monomer, of a low molecular weight, unsaturated polymer of butadiene or isoprene or copolymers thereof with styrene or acrylonitrile. In addition, a process for preparing such elastomer compositions is also provided, together with the vulcanization of such elastomers and the resulting vulcanized polyacrylate.
