Open the CIPO recordAbstract From the Canadian patent
Novel compounds of the general formula (m = 0 or 1; m = 2 or 3 and ? = H or CH3) are produced by reacting a 2-aminoalkyl alkyene urea with as allyl ester of a carbonylic acid. Among the particular allyl esters disclosed as reactants are dially carbonate allyl and methallyl chloroformate, diallyl and dimethallylexalate. The recovered allyl esters of the alkyleneureido amic acid compounds find particular use as functional comonomers for imparting wet adhesion properties to emulsion systems containing vinyl ester polymers used in paints and coating compositions. -1-
