SULFUR ACID FUNCTIONALIZED LATEX POLYMER |
摘要 |
The present invention is a process for preparing a multistage polymer by contacting under emulsion polymerization conditions an acrylic monomer, a sulfur acid monomer, and a phosphorous acid monomer as described herein. The present invention is also a composition comprising a nonionic surfactant and a stable aqueous dispersion of polymer particles comprising structural units of butyl acrylate, methyl methacrylate, a sodium vinylbenzenesulfonate, and phosphoethyl methacrylate; wherein the polymer particles have a Tg of less than 10° C. The composition of the present invention is useful as a binder for coatings compositions. |
