Abstract
The present invention has for its object to provide a novel organic zinc catalyst showing very high polymerizing activity in the reaction for producing a poly(alkylene carbonate) from carbon dioxide and an epoxide as well as a method of producing a poly(alkylene carbonate) using the same.The present invention provides an organic zinc catalyst to be used for the reaction for producing a poly(alkylene carbonate) from carbon dioxide and an epoxide, which is obtained by reacting a zinc compound, an aliphatic dicarboxylic acid and an aliphatic monocarboxylic acid in a mole ratio of 0.0001 to 0.1 relative to the aliphatic dicarboxylic acid.
