摘要： Novel organosilicon compounds having in a molecule at least one maleimido group bonded to a silicon atom through a Si-C linkage, synthesized by reaction of a derivative of maleic anhydride with an organosilicon compound having an amino-substituted hydrocarbon group bonded to the silicon atom. The reaction proceeds in two steps, the first step being addition of the amino group to the maleic anhydride derivative to form an amide structure and the second step being dehydration of the amide structure to form a maleimido ring. The organosilicon compounds having remarkable photosensitivity can be polymerized and cured on exposure to ultraviolet light, and the cured films are insoluble in organic solvents.
