ABSTRACT:
Ureido-functional ethylenically unsaturated copolymerizable amide monomers are disclosed which are the adduct formed by reacting an aminoalkyl alkylene urea, preferably aminoethyl ethylene urea, with substantially a stoichiometric amount, based on the amine functionality present, of a maleic anhydride compound in solution in N-methyl pyrollidone. The reaction is carried out at a temperature in the range of 80.degree. C. to 130.degree. C. to form an unsaturated carboxyl-functional amide. To provide amide monomers which are particularly useful for improving the adhesion of aqueous emulsion copolymer used to form latex paints, the carboxyl functionality in the amide is consumed by esterification with an epoxide, such as propylene oxide, to provide an acid value of less than 10.
