COPOLYMERS USEFUL AS DEMULSIFIERS AND CLARIFIERS

摘要

A copolymer useful as a demulsifier or water clarifier may be prepared by polymerizing at least one aromatic monomer having one or more polymerizable double bonds; at least one oleophilic monomer having one or more polymerizable double bonds; at least one ionizable monomer having a polymerizable double bond; and at least one hydrophilic monomer having one or more polymerizable double bonds, under polymerization conditions sufficient to prepare a copolymer. The copolymer may, in some embodiments, be prepared and used as a latex.
