Abstract

After general introduction for hyperbranched polymers, hyperbranched polysiloxysilanes (HBPS) were introduced as new functional polymers. Vinyl terminated HBPS was synthesized starting from AB2 type monomer by hydrosilylation reaction. Vinyl group can be converted various functional groups such as carboxylic acid and alcohol. HBPS had strong interaction to inorganic surface. As an example of this phenomenon, silica gel bead for HPLC was modified with thermo sensitive polymers. The resulting bead was successfully applied to Green Chronatography.
