The present invention provides novel silyl 2-amidoacetates and silyl 3-amidopropionates which are the reaction products of azlactone and silanol reactants. The novel products result from nucleophilic addition of a soluble or insoluble, low or high molecular weight reactant containing one or more silanol groups and a soluble or insoluble, low or high molecular weight reactant containing one or more azlactone groups. The reaction products provide for high adhesion between the siliceous and azlactone reactants, as would be useful as protective coatings particularly on silicon-containing materials. It has been recognized in the present invention that silyl 2-amidoacetates and silyl 3-amidopropionates are useful linkages between silanol and azlactone derived materials.
