摘要： This invention provides a process for preparing novel hydrophobically associating polymers containing cationic functionality which are useful for clean-up of waste waters containing organic contaminants. These water soluble polymers contain both water soluble and water insoluble monomers. The water soluble monomers are acrylamide (AM) and a salt of an unsaturated amine base (C), and the water insoluble monomer is a higher alkyl(meth)acrylamide or alkyl(meth)acrylate (R). These polymers are referred to as CRAM. The process relies on the dissolution of the water insoluble monomer(s) into an aqueous solution of water soluble monomers by means of a water miscible mutual cosolvent. The type and concentration of miscible solvents are chosen to produce a clear, uniform, homogeneous aqueous solution of the hydrophobic monomers in the presence of both nonionic and cationic water soluble monomers and, in addition, the reaction medium remains a clear, uniform, homogeneous mixture with no phase separation as the reaction proceeds to completion. Redox or free radical initiators are used to copolymerize both the water soluble and water insoluble monomers, forming terpolymers of ethylenically unsaturated amine base salts, alkyl(meth)acrylamides of alkyl(meth)acrylates and acrylamide. These polymers provide exceptional clean-up of waste waters containing organic contaminants. Also they are very effective for resolving oil-in-water emulsion, as such as those found in oil production.

摘要： This invention describes novel hydrophobically associating terpolymers containing sulfonate functionality which are useful as aqueous fluid rheology or flow modifiers. These high molecular weight water soluble polymers contain both water soluble and water insoluble monomers. The water soluble monomers are acrylamide (AM) and a salt of an ethylenically unsaturated sulfonic acid (S) and the water insoluble monomer is a higher alkyl acrylamide (R). These polymers are referred referred to as SRAM. The process for their preparation relies on solubilizing the water insoluble monomer into an aqueous micellar solution containing one or more surfactants and the water soluble monomers. The surfactants are specifically selected to enable homogeneous dispersion of the hydrophobic monomer(s) in the presence of anionic sulfonate containing monomers. Redox or free radical initiators are used to copolymerize both the water soluble and water insoluble monomers, forming terpolymers of ethylenically unsaturated sulfonic acids, alkylacrylamides and acrylamide. Aqueous solutions of these hydrophobically associating polymers exhibit enhanced viscosification, reduced salt sensitivity and other desirable rheological properties found useful in a variety of applications.

摘要： This invention describes novel hydrophobically associating ter or tetra polymers which can contain sulfonate functionality which are useful as aqueous fluid rheology or flow modifiers. These high molecular weight water soluble polymers contain both water soluble and water insoluble monomers. The water soluble monomers are N, N dimethylacrylamide acrylamide (DMA) and optionally a salt of an ethylenically unsaturated sulfonic acid (s) or N-vinylpyrrolidinone or a metal acrylate and the water insoluble monomer is a higher alkyl acrylamide (R). The process for their preparation relies on solubilizing the water insoluble monomer into an aqueous micellar solution containing one or more surfactants and the water soluble monomers. The surfactants are specifically selected to enable homogeneous dispersion of the hydrophobic monomer(s) in the presence of anionic sulfonate containing monomers. Redox or free radical initiators are used to copolymerize both the water soluble and water insoluble monomers, forming terpolymers of dimethylacrylamide, alkylacrylamides and acrylamide, and optionally an anionic sulfonate or carboxylate monomer. Aqueous solutions of these hydrophobically associating polymers exhibit enhanced viscosification, reduced salt sensitivity and other desirable rheological properties found useful in a variety of applications.

摘要： Novel hydrophobically associating terpolymer compositions containing cationic functionality are described. These water soluble or water dispersible polymers contain both water soluble and water insoluble monomers. The water soluble monomers are ethylenically unsaturated nonionic monomers, such as acrylamide (AM), and cationic monomers, such as a salt of an amine base (C), such as 3-methacrylamidopropyltrimethylammonium chloride (MAPTAC), 2-methacrylatoethyltrimethylammonium chloride (METAC) and diallyldimethylammonium chloride (DMDAAC). The hydrophobic or water insoluble monomer is a higher alkyl(meth)acrylamide or alkyl (meth)acrylate (R). These polymers are referred to as CRAM. While the novel compositions of this invention impart unusual properties to water based fluids, they are extremely efficient for clean-up of waste waters containing organic contaminants and for breaking oil-in-water emulsions.

摘要： Disclosed is a method for dispersing an oil spill on sea water which method comprises applying to the oil spill surface an effective amount of: (i) a blend of one or more hydrophilic and one or more lipophilic surfactants whose ratio is so adjusted that they will form microemulsions with the sea water and the oil to be dispersed, (ii) a solvent which is miscible with the oil to be dispersed and in which the blend of surfactants is substantially soluble, and (iii) from 0 to about 10 wt. % water. The blend of surfactants is such that it lowers the interfacial tension between the oil to be dispersed and the sea water to less than about 250 mdynes/cm when the blend is used at a treat rate of less than about 1 to 100 by weight, based on the weight of the oil to be dispersed.

摘要： The present invention teaches an improved process for clean-up of waste waters containing organic contaminants. In addition, the process is useful for breaking or resolving oil-in-water emulsions, such as those produced during oil recovery operations. Both the extent of clean-up based on residual oil left in the waste water and the efficiency of clean-up based on the treat rate of additive have been found to be significantly improved using the novel process of this invention. The novel process involves the use of a low level of a water dispersible terpolymer consisting of acrylamide, acrylic acid or its salts, and alkylacrylamide or alkylacrylate or alkylmethacrylate; or copolymers consisting of acrylamide and alkylacrylamide or alkylacrylate or alkylmethacrylate alone or in combination with a cationic species used to control the charge, usually negative charge reduction to near neutral, of the oil or organic contamination droplets in the emulsion being treated. The process of this invention is effective for the clean-up of waste waters containing organic contaminants and for the breaking of oil-in-water produced emulsions.

摘要： Novel water soluble copolymers of acrylamide, oil soluble higher alkylacrylamide and alkali metal acrylate have been found to provide efficient viscosification of water or brine. The process for synthesizing them relies on the complete solubilization of the water insoluble monomer into an aqueous solution of the water soluble monomer(s) by means of a suitable water soluble surfactant. A redox initiator system is used in conjunction with high monomer concentration and a low reaction temperature. The surfactant chosen and its concentration is one that produces a clear, uniform, homogeneous mixture in the presence of the monomers and gives a product which remains a clear uniform, homogeneous mixture with no phase separation as the reaction proceeds toward completion. The molecular weight of the resulting polymer after isolation from the surfactant is sufficiently high that it gives an intrinsic viscosity greater than about 12 dl/g.
