Lactide were investigated . the key factors affecting the polymer intrinsic viscosity were found to be monomer recrystallization times , stannous octoate concentration and polymerization time . the thermal stabilizing agent did not significantly affect the polymer molecular weight . the polymer with a viscosity average molecular weight beyond 200000 was fairly reproducible by optimizing the polymerization conditions . it was found that poly 單體重結晶次數辛酸亞錫濃度聚合時間等條件均是影響聚合物特性粘數的重要因素。熱穩定劑對聚丙交酯的分子量幾乎沒有影響。優化聚合條件可以獲得粘均分子量大于200000的聚丙交酯材料，聚合結果具有良好的重復性。 |

The main work and the conclusion of the article are : ( 1 ) give a suggestion on the reaction mechanism and the principle of catalyst selection . ( 2 ) by comparison of the catalyst activity of solid superacid with the zinc oxide , stannous chlorde and tin ( ii ) octate in the synthesis reaction . we find that although its activity is lower than tin ( ii ) octate , obviously higher than that of traditional zinc oxide and stannous chlorde . from the point of preparation cost , we select solid superacid as catalyst 但從催化劑的制備成本和工藝的角度選擇，固體超強酸具有明顯的優勢； ( 3 )制備一系列單組元和雙組元硫酸促進氧化物固體超強酸，并用于丙交酯的合成反應，篩選具有最佳活性的固體超強酸催化劑： ( 4 )使用so2 - 4 / zno - sno2 ( 2 ： 1 ) la3 +固體超強酸作催化劑，反應脫水時間1 |
