Abstract
Polymer latex (e.g., butadiene-styrene-itaconic acid copolymer latex) resulting from aqueous emulsion polymerization in the presence of conventional anionic emulsifying agent (e.g., dodecyl benzene sulfonate) has increased particle size and improved stability if a lignosulfonate salt (e.g., sodium lignosulfonate) is further employed as an emulsion modifier in the emulsion polymerization process. The resulting latex is useful for carpet scrim application.
