ABSTRACT:
The invention provides a novel class or organosilane compounds having a methacryloxy group and one or more of alkenyloxy groups bonded to the silicon atom as represented by the general formula ##STR1## in which R.sup.1 is a monovalent hydrocarbon group having from 1 to 8 carbon atoms, R.sup.2, R.sup.3 and R.sup.4 are each a hydrogen atom or a monovalent hydrocarbon group having from 1 to 8 carbon atoms, m is an integer of 3, 4 or 5 and n is a number of zero, 1 or 2. The organosilane compound, e.g. 3-methacryloxypropyl-containing alkenyloxysilanes can be readily prepared by the addition reaction of allyl methacrylate and a corresponding alkenyloxysilane having a hydrogen atom directly bonded to the silicon atom in the presence of a platinum catalyst. The organosilane compounds are useful as a coupling agent to increase adhesive bonding strength between inorganic and organic materials.
