manufacture example 1
[0140] Manufacture of organozinc catalysts
[0141] 7.73g (95mmol) zinc oxide, 12.3g (100mmol) glutaric acid, 0.114g (2 mmol) acetic acid and 76.0 g toluene. Subsequently, the temperature was raised to 55° C. while nitrogen gas was introduced into the reaction system at a flow rate of 50 mL / min, followed by stirring at the same temperature for four hours to allow reaction. Then, the temperature was raised to 110° C., and the mixture was stirred at the same temperature for two hours for azeotropic dehydration to remove water. The reaction mixture was then cooled to room temperature, resulting in a slurry containing the organozinc catalyst.
manufacture example 2
[0143] Manufacture of Polypropylene Carbonate
[0144] The atmosphere of a 1L autoclave equipped with a stirrer, a gas introduction pipe, and a thermometer was replaced with a nitrogen atmosphere in advance, and 39.1 g of the slurry containing the organic zinc catalyst obtained in Production Example 1 (containing 45 mmol of the organic zinc catalyst), 192.4 g dimethyl carbonate and 26.1 g (450 mmol) propylene oxide. Subsequently, carbon dioxide was added thereto with stirring so as to fill the reaction system with carbon dioxide until the reaction system was 1.0 MPa. After that, the temperature was raised to 60° C., and a polymerization reaction was performed for eight hours while supplying carbon dioxide consumed by the reaction. After the reaction was completed, the autoclave was cooled and decompressed, and the reaction mixture was filtered and dried under reduced pressure, thereby obtaining 40 g of polypropylene carbonate. The obtained polypropylene carbonate had a mass ...

[0152] Manufacture of Polypropylene Carbonate
[0153] 40 g of polypropylene carbonate was obtained in the same manner as in Production Example 2 except that the polymerization reaction time was changed from eight hours to ten hours. The mass average molecular weight of the obtained polypropylene carbonate was 330,000 (Mw / Mn=10.02).
