Copolymerizations of vinyl silanes

Abstract

Abstract A brief experimental investigation was made of the copolymerization of twelve alkoxysilanes with monochlorostyrene, vinyl chloride, and acrylonitrile. These new monomers include vinyltrimethoxy‐, vinyltriethoxy‐, vinyltriisoproxy‐, vinylmethyldiethoxy‐, vinylethyldiethoxy‐, and vinylphenyldiethoxy‐silanes as well as allyl‐, propenyl‐, 2‐butenyl‐, Δ 3 ‐cyclohexenyl‐, 6‐triethoxysilylbicyclo [2.2.1]heptane‐2, and α‐chlorovinyl‐triethoxysilanes. No copolymerization took place with monochlorostyrene. In the copolymerizations with vinyl chloride, and with acrylonitrile, the reactivity ratio r 2 was assumed to be zero and the value of r 1 determined.
