摘要： This invention provides a process for preparing novel hydrophobically associating terpolymers 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 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 cationic monomers, such as 3-methacrylamidopropyltrimethylammonium chloride (MAPTAC), 2-methylacrylatoethyltrimethylammonium chloride (METAC), or diallyl dimethylammonium chloride (DMDAAC). 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 or 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 emulsions, such as those found in oil production.

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： This invention relates to a method for enhanced recovery of petroleum from a subterranean oil-bearing formation. More particularly, this invention relates to secondary or tertiary recovery of oil employing a polymer thickened aqueous drive fluid. The polymeric viscosifier for the drive fluid is selected from a class of hydrophobically associating water soluble polymers containing one or more water soluble monomers and a water insoluble monomer or group. The water soluble groups are acrylamide and a salt of an ethylenically unsaturated sulfonic acid and the water insoluble group is a higher alkyl acrylamide. These polymers, when dissolved in an aqueous brine solution, have the ability to substantially increase the viscosity of the solution. The control of displacement fluid mobility results in more uniform sweep efficiency and improved oil recovery. In addition, aqueous solutions of these hydrophobically associating polymers exhibit enhanced viscosification, reduced salt sensitivity and other desirable rheological properties found useful in chemically enhanced oil recovery processes.

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： 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.
