Abstract
3-(Vinylbenzyloxy)propylsilane compounds represented by the general formula, CH.sub.2 CH.PHI. CH.sub.2 OCH.sub. CH.sub.2 CH.sub.2 SiR.sup.1.sub.n (OR.sup.2).sub.3-n (wherein R.sup.1 and R.sup.2 each represent a hydrocarbon residue containing 1 to 4 carbon atoms, and n represents an integer from 0 to 2) are provided as novel styrene skeleton-containing alkoxysilane compounds which are highly useful as silane coupling agent or polymerizing monomer.
