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. This process includes applying the lubricant composition to at least one of the surfaces. The lubricant composition in this instance comprises a superabsorbent polymer combined with a material for decreasing friction between moving surfaces, wherein the material for decreasing friction comprises a petroleum lubricant, water, synthetic lubricant, grease, solid lubricant or metal working lubricant, and optionally an additive.

A lubricant composition is disclosed comprising a superabsorbent polymer combined 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. In the composition, the material for decreasing friction comprises 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 method of lubricating a surface is also disclaosed comprising coating said surface with the lubricating composition comprising the superabsorbent polymer combined with a material for decreasing friction between moving surfaces, wherein the material for decreasing friction comprises a petroleum lubricant, water, synthetic lubricant, grease, solid lubricant or metal working lubricant, and optionally an additive.

A substrate is coated with an essentially water-free composition. The composition includes a superabsorbent polymer that absorbs from about 25 to greater than 100 times its weight in water and a material for lubricating the substrate. The superabsorbent polymer may be a polymer of acrylic acid, acrylamide or acrylate. Also included is a method for protecting a substrate from the effects of water or water migration.

The application of film-forming compositions to aquatic sites, especially aquatic breeding sites for control of surface-active aquatic breeding insects other than black flies, especially for immature mosquitos, has been found to be enhanced when different compounds than those suggested in the prior art are used. The compounds according to the present invention comprise film-forming chemicals which are biodegradable, nonionic, insoluble or partially soluble in water, and include C , C , C , C , C , and C alcohol ethoxylates, propoxylates, and/or alkoxylates with an average of one (1) to five (5) moles of ethylene and/or propylene oxide per mole of alcohol, and mixtures thereof. The compositions may be applied directly as liquids or released into the aquatic environment from a carrier, such as a biodegradable, water-erodible, water-soluble or water-dispersible carrier. Compositions may also be formulated with chemical or microbial pesticides prior to application as a liquid or from a carrier for enhanced single stage or multistage insect control.

Controlled release compositions of matter are disclosed comprising complexes for treating a population of ore or more aquatic organisms in a column of water. The complexes comprise a least one system wherein the system comprises at least one bioactive agent as a component selected for treating a population of aquatic organisms, at least one carrier component, and at least one coating component for regulating the controlled release rate and release profile of the bioactive agent in water or at least one bioactive agent and one joint-function component that can serve as both a carrier and coating to regulate the controlled release rate and release profile of the bioactive agent in water, with or without optional binder components and/or additional formulation materials. The components are selected to sink or float so that the complexes will permeate and/or remain in any planar or volumetric segment of a water column for a period of time that is sufficient to effectively treat a population of aquatic organisms. Methods for treating a column of water are also disclosed which comprises delivering the compositions to a column of water or to a dry preflood area (pretreatment) that will develop in a column of water or a flood area. The composition and process can also be used to treat terrestrial organisms.

The invention provides contaminant-reducing agent delivery compositions that are useful for the control of organic or inorganic contaminants in aquatic or terrestrial environments. The compositions comprise one or more superabsorbent solid organic polymers and at least one contaminant-reducing agent. These superabsorbent polymers act as the primary carriers of one or more contaminant-reducing agents effective for the control of organic or inorganic contaminants in aquatic or terrestrial environments. Contaminant-reducing agents include film-forming agents, microbial agents, nutrient agents, and mixtures thereof. The invention also provides a method to entrap and accumulate organic and inorganic contaminants in one or more superabsorbent polymer compositions containing no contaminant-reducing agent.
