ABSTRACT:
Improved core-shell polymers having an alkali-insoluble core and an alkali-soluble shell are prepared by emulsion polymerization of the core-shell polymers utilizing compounds which chemically graft the core and shell together. The core-shell polymers exhibit improved solvent stability, water resistance, heat resistance and rheology. The polymers are useful in application such as inks, coatings and varnishes, floor polishes, leather treatment, cement formulations, and as a seed for further emulsion polymerization.
