Disclosed herein are core-shell polymers having an alkali-insoluble, emulsion polymer core and an alkali-soluble, emulsion polymer shell physically or chemically attached or associated with said core so that upon dissolving said shell with alkali, a portion of said shell remains attached or associated with said core. Also disclosed are compositions wherein said shell polymer has been neutralized and substatially, but not totally, dissolved so as to form a blend of neutralized core-shell polymer and an aqueous solution of neutralized shell polymer. The polymers are useful in applications such as inks, floor polishes, leather treatment, cement formulations, coatings, stains and varnishes and as a seed for further emulsion polymerization. |
