Abstract: Liquid hydroxyurethane products having cyclocarbonate end groups are prepared by reacting a molar excess of a bis-carbonate of a bis-glycidyl ether of neopentyl glycol or 1,4-cyclohexanedimethanol with a polyoxyalkylenediamine such as a polyoxypropylenediamine. These products are useful for the preparation of polyurethanes, polyurethane polyols, polyester polyurethane polyols, and polycarbonate polyurethane polyols.

Abstract: A process for the dissolution of cured polyester resins is disclosed.

Abstract: Synthetic lubricant base stocks may be prepared in good yield by oligomerizing linear olefin monomers using certain acidic calcium montmorillonite clay catalysts. When the oligomers are prepared at a temperature greater than about 200.degree. C., and any unreacted linear olefin monomer is removed, oligomers having an iodine value less than about 3 mg/g are obtained. An even lower iodine value is obtained when a hydrocarbon possessing a tertiary hydrogen is mixed with the linear olefin feed, and the mixture is contacted with the clay at a temperature greater than about 200.degree. C. Little or no hydrogenation may be required of oligomers prepared in this manner to obtain base stocks suitable for use as synthetic lubricants.

Abstract: Vinyl monomers are polymerized in high yield to water-soluble polymers or copolymers by free radical polymerization of an aqueous reaction mixture containing the vinyl monomer(s), an UV-activated photoinitiator and a heat-activated chemical initiator. The polymerization is initially carried out by exposing the monomer mixture to UV radiation to activate the photoinitiator and then is carried out under the influence of free radicals produced by the chemical initiator.

Abstract: A process for the dissolution of polyurethane foams is disclosed. A polyurethane foam may be dissolved, or removed from a substrate, by contacting the polyurethane foam with 1,2-dialkyl imidazole, alone or as a co-solvent.

Abstract: A process is disclosed for preparing synthetic lubricant base stocks having improved properties. Synthetic lubricant base stocks may be prepared in good yield by oligomerizing linear olefins using certain acidic montmorillonite clay catalysts. When a mixture of poly(isobutylene) and long-chain linear olefin, in which up to about 10 wt. % of the mixture is poly(isobutylene), is co-reacted in the presence of these catalysts, a synthetic lubricant base stock having a high viscosity and a high viscosity index is prepared.

Abstract: An improved process is disclosed for preparing synthetic lubricant base stocks. Synthetic lubricant base stocks are prepared in good yield by oligomerizing linear olefins using certain acidic calcium montmorillonite clay catalysts which have aluminum nitrate deposited thereon.
