Abstract
Disclosed are compounds produced by a process comprising the step of reacting an amine reactant with an epoxide reactant to form a hydrolytically stable carbon-nitrogen bond therebetween, wherein at least one of the amine or epoxide reactants comprises a terminal alkoxysiyl group. Also disclosed are curable compositions comprising the compounds of the present invention and the cured products derived therefrom.
