Abstract
Abstract Novel organosilane compounds of the following general formula <IMAGE> in which R1 is a hydrogen atom or a methyl group, R2 and R3 are independently an unsubstituted or substituted monovalent hydrocarbon group, and n is an integer of 1, 2 or 3. The compounds are reactive with other reactive group-bearing copounds and are effective for potting, sealing or coating of electric and electronic parts.
