Abstract
Abstract Polyfunctional ester oxazolidines of the general formula WHEREIN Z is a polyvalent alkylene, arylene, or alkenylene radical, R1 and R2 are hydrogen, alkyl, phenyl, or benzyl, X and Y are divalent (C2-C3)alkylene radicals, and N IS AN INTEGER EQUAL TO THE VALENCE OF Z, produced by means of a transesterification process are useful in preparing or formulating adhesives, caulks, lacquers, paints, varnishes, leather impregnants and moisture-cured coating systems.
