Abstract
Hyperbranched polysiloxysilanes (HBPSs), with a variety of terminal functional groups (vinyl, epoxy, carboxyl and hydroxyl), were synthesized by the self-polymerization of an $AB_3$ type monomer of tris(dimethylvinylsiloxy) silane, with subsequent end-functionalizations, such as epoxidation and radical addition reaction, respectively. The ratio of the $\alpha-and$ $\beta-addition$ linkages in the HBPS polymerized by hydrosilylation of the $AB_3$ monomer was found to be approximately 1 to 3. The thermal stability and solubility were affected by the terminal functional groups.
