  • Patent number: 6844287
    Abstract: The present invention provides a process for preparing supported zinc dicarboxylate catalysts with high activity for the copolymerization of carbon dioxide and epoxides by supporting zinc dicarboxylate on silica support. The zinc dicarboxylate may be synthesized from zinc oxide and dicarboxylic acid such as succinic acid, glutaric acid, adipic acid, pimelic acid and suberic acid. The silica support can be selected from the group consisting of aerosil, silica gel for chromatography or reagent grade silicon dioxide. The supporting process is performed in a planetary ball grinder under vacuum.
