| 摘 要： | 研究了Nd（naph）3-Al（i-Bu）3（naph为环烷酸）催化降冰片烯（NB）与甲基丙烯酸丁酯（BMA）共聚反应的条件及其催化剂钕铝比的影响.结果表明：稀土催化剂在温和的反应条件下有较好的催化性能;共聚反应可以在室温下进行,反应温度的增加使共聚物收率略减;共聚物分子量和分子量分布随NB/MA摩尔比的增加而变小,共聚物分子量分布较小,Mw/Mn=1.65～2.22;共聚物收率随Al/Nd摩尔比而变化,较合适的Al/Nd摩尔比为5.5.

| Abstract: | The characteristics of copolymerization of norbornene and Butyl methacrylate by Nd（naph）3- Al（i-Bu）3 and the structure of the copolymer are presented in the paper. All polymerization reactions are carried out under nitrogen atmosphere using syringe technique. The molecular weight distribution is Mw/Mn=1.65-2.22, The molecular weight of copolymer varies with the change of NB/MA molar ratio. Molecular weight and its distribution of copolymer decrease as molar ratio of NB/MA increases. The copolymerization can be performed in the solvents such as aromatic hydrocarbon and obtained at room temperature. However, the increasing reaction temperature causes a decrease of the copolymer yield. The yield of copolymer is in variant according to the change of Al/Nd molar ratio. The suitable Al/Nd molar ratio is found to be 5.5. |
