Disclosed are a novel hyperbranched polymer which is optically and thermally stable and another novel hyperbranched polymer which is water-soluble, and optically and thermally stable. Also disclosed are methods for producing them. Specifically disclosed is a hyperbranched polymer obtained by reducing a molecular terminal (dithiocarbamate group) of a hyperbranched polymer, which is obtained through living-radical polymerization of a dithiocarbamate compound having a vinyl group structure and a maleic anhydride, to a hydrogen atom. Also disclosed is a hyperbranched polymer obtained by hydrolyzing the maleic anhydride unit of the above-obtained polymer, or a hyperbranched polymer obtained by hydrolyzing the maleic anhydride unit of the hyperbranched polymer obtained through living-radical polymerization of a dithiocarbamate compound having a vinyl group structure and a maleic anhydride. |
