Abstract
Abstract Organosilanes are provided having at least one chemicallycombined aliphatically unsaturated imido organic radical, such as a maleimido-substituted organosilane and a method for making these materials. For example, reaction can be effected between an aliphatically unsaturated dicarboxylic acid anhydride and an aminoorganoalkoxysilane. In certain instances, amido acid precursors of such unsaturated imido-substituted organosilanes also can be made. The aliphatically unsaturated imido-substituted organosilanes of the present invention can be employed to impart improved surface characteristics to cellulosic substrates and to make aliphatically unsaturated imido-substituted organopolysiloxanes.
