Abstract: A process is disclosed for manufacturing a lubricant composition comprising combining a superabsorbent polymer with a material for decreasing friction between moving surfaces. The superabsorbent polymer absorbs from about 25 to greater than 100 times its weight in water and may comprise a polymer of acrylic acid, an acrylic ester, acrylonitrile or acrylamide, including co-polymers thereof or starch graft co-polymers thereof or mixtures thereof. A product produced by the process includes the material for decreasing friction comprising a petroleum lubricant containing an additive, water containing an additive, synthetic lubricant, grease, solid lubricant or metal working lubricant, wherein the synthetic lubricant, grease, solid lubricant or metal working lubricant optionally contain an additive. A process comprising controlling the delivery of a lubricant to at least one of two moving surfaces in order to decrease friction between said moving surfaces, is also disclosed.

Abstract: A photoacid generator compound P+A?, comprises an antenna group P+ comprising a cation that generates protons upon interaction with light, and A? comprising a weakly coordinating peracceptor-substituted aromatic anion that does not contain fluorine or semi-metallic elements such as boron. In one embodiment, such anions comprise the following compounds 4, 5, 6 and 7, wherein E comprises an electron-withdrawing group and the removal of one proton generates aromaticity. P+ comprises an onium cation that decomposes into a proton and other components upon interaction with photons. P+ may comprise an organic chalcogen onium cation or a halonium cation, wherein the chalcogen onium cation in another embodiment may comprises an oxonium, sulfonium, selenium, tellurium, or onium cation, and the halonium cation may comprise an iodonium, chlorine or bromine onium cation. A novel compound comprises TPS CN5.
