Abstract: Polyunsaturated compounds useful in radiation curable compositions are made by reacting p-vinylphenol and a polyisocyanate in the ratio of one mole of p-vinylphenol for each isocyanate group of the polyisocyanate.

Abstract: Improved iron oxide catalysts for the dehydrogenation of ethylbenzene to styrene are made by forming a blend of chromium oxide and yellow iron hydrate and heating the blend to convert the yellow iron hydrate to red iron oxide prior to forming the catalyst.

Abstract: Dual action sunscreen compositions capable of both moisturizing the skin and protecting it from sunburn are made from a cationic guar, a cationic acrylic polymer and an ultraviolet absorbing sunscreening agent.

Abstract: Acrylate polyesters are made by the reaction of a diol, a dibasic acid anhydride and glycidyl acrylate. When formulated into radiation curable compositions, the compositions can be used as coating, inks, and adhesives which cure at high rates when exposed to actinic radiation.

Abstract: A desiccant cartridge for a container, which contains moisture-sensitive product, wherein said desiccant cartridge contains at least one outside-connection opening via which the desiccant cartridge is joined to the surrounding air, a desiccant being contained in a cartridge casing. A surrounding-air duct extends between the outside-connection opening and the desiccant. This surrounding-air duct forms a long diffusion path in relation to the breathing cross-sectional area of the desiccant cartridge.

Abstract: Polyunsaturated compounds useful in radiation curable compositions are made by reacting p-vinylphenol and a polyisocyanate in the ratio of one mole of p-vinylphenol for each isocyanate group of the polyisocyanate.

Abstract: Curable compositions are made from blends of polycyanate ester of polyhydric phenols and amorphous, aromatic thermoplastic resins which are initially soluble in the polycyanate ester but which phase separate during curing of the polycyanate ester.

Abstract: Transition metal on an inert stable carrier hydrogenation catalysts are stabilized with a coating of a fatty amine and an alkane wherein the fatty amine-alkane coating has a melting point of about 130.degree. C. to about 180.degree. F.

Abstract: Quaternary ammonium containing monomers, represented by the formula: ##STR1## wherein R.sub.1 is H or methyl, R.sub.2 is an alkyl group containing 6 to 22 carbon atoms, D is an alkylene group containing 1 to 4 carbon atoms, or a hydroxylalkylene group containing 2 to 4 carbon atoms and X is an anion, are polymerized to form polymers useful in hair care preparations.

Abstract: Modified acrylic copolymer compositions are made by polymerizing acrylic monomers in admixture with a citric ester. Such compositions are useful as pigment grinding vehicles and as vehicles for thermosetting coatings.

Abstract: Stable emulsion are made from hydrocarbon liquids, water and a water-soluble polysaccharide, plus a fatty acid alkanol amide surfactant. These emulsions are readily dispersed in water to form viscous solutions useful in the clarification of waste waters, in paper making operations and in oil service operations.

Abstract: Heat curable coating compositions particularly suitable as coatings for metal can ends are made from aqueous dispersions of epoxy resins, acrylic resins which are copolymers of polymerizable acids and other monomers, phenoxy resins, alkylated phenol novolac resins and resol resins.

Abstract: In an aqueous process for derivatizing polygalactomannan gums, the derivatized product prior to washing is reacted with a water soluble aluminum salt. The resulting products hydrate readily under alkaline pH conditions.

Abstract: It has been discovered that by adding one or more strong organic carboxylic acids to conventional acrylate and/or methacrylate based adhesive compositions, the bonding characteristics thereof change dramatically.Thermoplastic materials whose bondability is most dramatically enhanced by the compositions of the present invention are nylon and blends of nylon and nylon-like materials with other polymers.Thermoset materials which exhibit dramatically enhanced bondability comprise homogeneous materials such as epoxies, and composite materials such as polyesters, urethanes, and/or epoxies, containing glass, minerals, and the like, which are polar or have hydrogen bonding capability.The present invention thus utilizes acrylate and/or methacrylate based adhesive compositions as a base material. To this base material is added an effective amount of one or more strong organic carboxylic acids, e.g., acids having a relatively high dissociation constant (K.sub.d or K.sub.ld).
