| Abstract: | The effects of temperature,concentration of catalyst and feeding rates of monomer on molecular weight and molecular weight distribution in polymerization of propylene oxide with DMC catalyst were discussed.Adding starter continuously can make molecular weight distribution narrow.Adjusting acid number of starter can reduce polymerization induction time. |
