Abstract
This invention relates to an improved continuous emulsion polymerization process. Specifically, this invention relates to an improved method for producing carboxylated styrene/butadiene latices. The improvement is characterized in that a reaction mixture containing specified reaction ingredients and only a portion of the primary monomers is charged to a first reaction zone followed by subsequent injection of the remaining portion of the primary monomers to the following reaction zone in a chain consisting of two or more reactors. The latices produced by the process of this invention have improved stability during polymerization and improved physical and application properties.
