ABSTRACT:
Terpolymer emulsions of vinyl acetate, vinyl chloride and ethylene are used in surface coatings, e.g. paints, and require certain properties for this application. The dry tensile strength and water uptake properties of such terpolymers is improved by adding monomer with the initiator during the reaction at rates which provide a reservoir of free monomer in the medium.
