Itaconic acid/2-acrylamido-2-methlpropanesulfonic acid (AMPS) copolymer as an oil well cement retarder
A copolymer has been prepared from 2-acrylamido-2-methylpropanesulfonic acid (AMPS) as the major component and itaconic acid as the minor component using an initiatior. The optimum reaction conditions were determined and the mechanism of reaction investigated. The structure of the coolymer was studied by IR spectroscopy. It was found that the properties of the polymer showed a significant variation with monomer ratio, amount of initiatior and reaction temperature, and the optimum combination of these were derived. Addition of the copolymer afforded a significant retardation in the thickening time of a cement slurry and it also had excellent dispersal and drag reducing properties and thus has the potential to be widely applied in oil well cementation.
