3-(vinylbenzyloxy)propyl silanes are of the general formula:
CH₂CH-benzylidene-CH₂OCH₂CH₂CH₂SiR¹n(OR²)3-n
wherein R¹ and R² each are a C1-4 hydrocarbon residue, e.g., alkyl, and n is 0.1 or 2.
Synthesis is from the corresponding 3-(vinylbenzyloxy)-1-propene, by reaction in the presence of a platinum catalyst with either a) a hydrogen silane HSi R¹n(OR²)3-n, or b) a hydrogen silane HSiR¹nX3-n, when the product is reacted with an alcohol of a C1-4 hydrocarbon residue and optionally with urea.
The novel silanes can be copolymerized with a monomer selected from styrenes, acrylates, methacrylates, vinyl esters, ethylene, propylene, vinyl chloride, butadiene, isoprene, chloroprene and α-olefins, or the silane is used directly to treat organic or inorganic material.
