    摘要: Monoethylenically unsaturated copolymerizable monomers are disclosed which improve the adhesion of copolymers (especially those produced by aqueous emulsion copolymerization to provide latex paint). These monomers are the reaction product of one equivalent of a monoethylenically unsaturated compound which resists homopolymerization and which carries a single isocyanate-reactive hydrogen atom, such as 2-hydroxypropyl monobutyl maleate, one mole of an organic polyisocyanate, such as 2,4-toluene diisocyanate, and sufficient alkyl alkylene urea carrying a single isocyanate-reactive hydrogen atom on the alkyl group, such as 2-hydroxyethyl ethylene urea, to consume the remaining isocyanate functionality on the polyisocyanate. An improved method of producing these monomers from a mixture of all three reactants is also disclosed.
