Abstract
Viscosity stable polymers containing bound carboxyl groups in latex form when compounded at high solids content and at a high pH are obtained in accordance with this invention when the latex is prepared by polymerizing butadiene or an acrylic or methacrylic ester with an unsaturated carboxylic acid in the presence of an olefin sulfonate emulsifier. The olefin sulfonates contain a major proportion of C.sub.14 to C.sub.16 aliphatic carbon atoms. By use of this emulsifier, high total solids, viscosity stable latexes can be obtained by direct polymerization.
