Abstract
Abstract Alkoxysilylbenzotriazoles are provided and method for making such materials. These alkoxysilanes have been found useful as UV stabilizers and as adhesion promoters for silicone top coat compositions which can be applied onto thermoplastic organic polymers to impart improved abrasion resistance and UV stabilization thereto.
