摘要： 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.

摘要： This invention is a method for making 1,2-substituted imidazoline compositions utilizing a polyamine mixture containing a high concentration of linear polyamine. The polyamine is either triethylenetetramine or tetraethylenepentamine. The polyamine mixture is reacted with a fatty acid, fatty dimer acid or the fatty esters thereof to yield the 1,2-substituted imidazoline composition. The highly linear polyamine provides higher yields of the imidazoline compound in the composition.

摘要： 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.
