Abstract

N-alkoxysilylalkyl-aspartic acid esters are prepared by the reaction of equimolar quantities of amino-alkyl alkoxysilanes with maleic or fumaric acid esters. These N-alkoxysilylalkyl-aspartic acid esters are particularly useful as reactants in the preparation of prepolymers containing alkoxysilane and urea groups.
