Abstract
A stable emulsion polymer is prepared by the emulsion polymerization of a vinyl monomer component in the presence of a base neutralized copolymer having a peak molecular weight not exceeding 50,000 of an olefinically unsaturated material selected from the group consisting of 1-decene, 1-dodecene, undecenylic acid and mixtures thereof and an ethylenically unsaturated anhydride containing material. The emulsion polymer is particularly useful for preparing coating compositions which have excellent physical properties.
