Abstract Synthetic methodology for a new monomer, (4-vinylphenyl)tris(dimethylsiloxy) silane (3), which can be polymerized to give either hyperbranched polymers or linear polymers has been developed. Hyperbranched polymers can be prepared from the monomer via hydrosilation. Monomer3 can undergo free radical polymerization, which yields a linear homopolymer. Copolymers with styrene have also been prepared. The resulting polymers, which contain pendant silicon hydride functionality, can be functionalized with a variety of reagents. The glass transition temperature was found to depend strongly on the amount of silicon incorporated into the polymers.
