| 摘 要： | 研究了高分子量聚碳酸1,2-丙二酯的碱催化水解反应,并通过核磁共振谱仪和气相色谱质谱联用仪对降解反应产物的解析,发现碱催化聚碳酸1,2-丙二酯水解是无规断链反应和解拉链反应共同作用的结果.结果表明高分子量聚碳酸1,2-丙二酯的碱催化水解是制备低分子量聚碳酸1,2-丙二酯的方法之一.

| Abstract: | The base catalyzed hydrolysis reaction of poly(propylene carbonate)(PPC),a highly alternative copolymer synthesized from carbon dioxide and propylene oxide,was investigated systematically in this report.The influences of reaction time,concentration of PPC solution,concentration of base(sodium hydroxide) solution,and residual zinc oxide on the degradation reaction were discussed.()~1H-NMR spectra were used to analyze the carbonate unit content in the degraded polymer,it was found that the carbonate unit in t... |
