Procedure

The above compound (Adduct I, was prepared by heating a mixture of 10.7 g (0.05 mole) of 2,4-dihydroxybenzophenone and 12.04 g (0.051 mole) of γ-glycidoxypropyltrimethoxysilane under nitrogen in the presence of 0.1 g of tetramethylammonium chloride. The mixture was stirred and gradually heated to 75°-80° C., then maintained at this temperature for 8 hours. During this period it changed into a homogeneous, viscous oil. An equivalent product was obtained when the reactants were heated at 80° C. for 4 hrs.
