General description

Dichloromethylvinylsilane reacts with dimethylsulphide borane to form organosilylborane, which further gets ammonolysized to form the polymer of the SiBCN.

Application

Dichloromethylvinylsilane was used as single molecular precursor for the deposition of β-SiC thin films and β -SiC nanowires by metalorganic chemical vapor deposition on bare Si 100 and Ni-coated Si 100 substrates. Dichloromethylvinylsilane was used in the synthesis and characterization of Tris(1-(dichloro(methyl)silyl)ethyl)borane,monomer.

Poly(methylvinylsiloxane)-bonded silica gel was synthesized by condensation reaction between silica gel and the hydrolysis product of methylvinyldichlorosilane. Graft polymerization of styrene or indene onto poly(methylvinylsiloxane)-bonded silica gel was carried out by gamma-ray irradiation and compared with that onto silica gel.
