Abstract:
The current invention provides a method to form a stable blend of polyacrylamide water-in-oil emulsion and breaker surfactants such as silicon polyether copolymer and linear or branched alcohol ethoxylate surfactants. The composition can be employed, for example, as a friction reducing additive for water based fracturing fluid, or a drilling mud additive.
Abstract:
A composition for treating an aqueous fluid includes an ionic polyacrylamide and a silicon polyether, The composition can be art oil-in-water emulsion or a water-in-oil emulsion. The ionic polyacrylamide can be an anionic polyacrylamide or a cationic polyacrylamide. The composition can be employed, for example, as a friction reducing additive for water based fracturing fluid, or a drilling mud additive.
Abstract:
A water swellable cross-linked polyacrylate elastomer comprising at least one phosphate or phosphonate moiety and method of preparation is provided. The elastomer can advantageously be included in skin treatment compositions. Swellable elastomers in accordance with the invention are particularly well suited for inclusion in skin tightening cosmetic products. The elastomers can be formulated to form a film. When applied to skin, an elastomer in accordance with preferred embodiments of the invention can adhere to the skin and shrink as it dries. This can provide a skin tightening, lifting and wrinkle smoothening effect upon drying. This effect can temporarily mask the appearance of wrinkles. The elastomer may be the reaction product of reaction components comprising an acrylate or methacrylate moiety-containing component having 3 to 60 carbon atoms and a phosphate or phosphonate moiety-containing component having 3 to 60 carbon atoms. The reaction components may further comprise a siloxane component.
