Ethylenediaminetetraacetic Acid → Potassium;prop-2-enamide;prop-2-enoate

참여 물질

반응 단계

The copolymer may be manufactured as follows: a water phase containing 199.1 g of acrylamide, 84.5 g of acrylic acid, 3.0 g of ethylenediaminetetraacetic acid, 0.2 g of potassium bromate, 60.3 g of potassium hydroxide and 342 g of water is homogenized with an oil phase containing 240 g of oil, 20 g of sorbitan monooleate, 0.2 g of 2,2'-azobis-(isobutyronitrile). The emulsion is then transferred to a suitable reaction vessel with stirring and is sparged with nitrogen. Polymerization is initiated and sustained by continuously adding a solution of sodium metabisulfite throughout the exotherm. The cooling is provided to maintain the temperature of the system between 35° C.-45° C. The polymerization is completed in about 6-10 hours to give an emulsion product of acrylamide/potassium acrylate copolymer. To produce a self-inverting product, 24 g of a breaker system composed of a 1.75:1 blend of the reaction product of nonylphenol with 6 moles of ethylene oxide and the reaction product of dinonylphenol with 24 moles of ethylene oxide is added.
