Abstract
The efficient synthesis of two new monomers, vinyltris(dimethylsiloxy)silane (2) and tris(dimethylvinylsiloxy)silane (3), was developed. Hydrosilation of these new A–B3 monomers affords highly branched starburst poly(siloxysilane) polymers. Polymerization of2 yields a polymer structure that has siliconhydride functional groups on the outer sphere. Polymerization of3 yields a polymer that has the same hyperbranched poly(siloxysilane) core as the polymer produced from2, but the outer sphere contains vinyl moieties. The presence of silicon-hydride or vinyl groups on the surface of both polymers allows functionalization of these materials with a wide variety of reagents.
