Abstract
Official abstract text for this publication.
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 multistage polymer is useful as a binder for coatings compositions.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process comprising: a) contacting together sodium 4-vinylbenzene sulfonate, a phosphorous acid monomer, and a first acrylic monomer, under emulsion polymerization conditions to form a stable aqueous dispersion of first polymer particles, then; b) contacting the dispersion of the first polymer particles with sodium 4-vinylbenzene sulfonate; and a second acrylic monomer under emulsion polymerization conditions to form a stable aqueous dispersion of m…
