Patent abstract
The present invention provides an inverse emulsion polymer having a dispersed phase composed of an aqueous solution of an acrylic polymer and a continuous phase composed of an ester of a fatty acid and a water-soluble alcohol. The present invention further includes a method of water treatment which includes adding the inverse emulsion polymer to an industrial water system and hydrolyzing the ester of a fatty acid and a water-soluble alcohol into a fatty acid salt. The inverse emulsion polymer may be used as a flocculant to clarify industrial water systems at elevated temperature and/or elevated pressure and high pH.
