    • PURPOSE: A manufacturing method of poly(alkylene carbonate) is provided to manufacture poly(alkylene carbonate) of which molecular weight and shape of polymer chain are accurate controlled by putting a compound comprising a hydroxyl group, containing phosphorous component as a molecular weight controlling agent into a carbon dioxide/epoxide copolymerization catalytic reaction. CONSTITUTION: A manufacturing method of poly(alkylene carbonate) comprises a step of alternately copolymerizing one or more epoxide compounds and carbon dioxide under the presence of a compound in chemical formula 5, by using a complex compound in chemical formula 1. The one or more epoxide compounds are selected from C2-C20 alkylene oxides, which is substituted or unsubstituted by halogen, C1-C20 alkyloxy, C6-C20 arloxy or C6-C20 ar C1-C20 alkyloxy, C4-C20 cycloalkylene oxides which is substituted or unsubstituted by halogen, C1-C20 alkyloxy, C6-C20 arloxy or C6-C20 ar C1-C20 alkyloxy, and C8-C20 styrene oxides which is substituted or unsubstituted by halogen, C1-C20 alkyloxy, C6-C20 arloxy or C6-C20 ar C1-C20 alkyloxy.
