摘要：Provided is preparation of poly(alkylene carbonate) through alternatingcopolymerization of carbon dioxide and epoxide. According to the disclosure, by
introducing a diepoxide compound to alternating copolymerization of carbon dioxide andepoxide compound using a metal(III) prepared with salen-type ligands containing
quaternary ammonium salt as a catalyst, some of the polymer chains may be cross-linkedto thus increase an average molecular weight of the copolymer and extend a distributionof molecular weight. A resin prepared according to this method may have highmechanical strength and rheological advantages.
