US 6,207,771 B1 · Method for producing polymers using micellar polymerization

Abstract

A process for forming a hydrophobically modified water soluble or water dispersible polymer by utilizing a micellar polymerization technique comprising the steps of: (1) providing a reaction medium including one or more water soluble or water dispersible monomers and one or more surface active agents or protective colloids; (2) incrementally adding one or more ethylenically unsaturated monomers having hydrophobic properties to said reaction medium; (3) initiating polymerization of said one or more water soluble or water dispersible monomers with said one or more ethylenically unsaturated monomers having hydrophobic properties; and (4) continuing polymerization of said one or more water soluble or water dispersible monomers with said one or more ethylenically unsaturated monomers having hydrophobic properties while incrementally adding said one or more ethylenically unsaturated monomers having hydrophobic properties to said reaction medium is provided.
