Abstract
The invention relates to polymerizable emulsifiers, methods of preparing the emulsifiers, and latex compositions comprising the emulsifiers. In particular, the invention relates to maleic anhydride propylene sulfonate adducts of rosin and/or fatty acid which can be substituted for the surfactants or emulsifiers traditionally employed in the preparation of butadiene derived latexes.
