Abstract

Multistage polymers predominantly stabilized by nonionic emulsifiers and derived from hard and soft monomer compositions containing vinyl esters, of which at least one monomer composition must contain an unsaturated compromisable organosilicon compound, are described.The plastic dispersions can be used as binders in emulsion paints and finishes and impart to these excellent scrub resistance in addition to good blocking resistance.
