| 摘 要： | 丙烯酸酯类极性单体的聚合反应通常采用自由基型引发剂。过渡金属化合物与烷酸铝所组成的配位催化剂对这类极性单体的催化聚合迄今仍处于研究阶段。我们在稀土催化环氧烷烃聚合的基础上曾研究了稀土钕的磷酸盐体系催化甲基丙烯酸甲酯、正丁酯的聚合。本文研究了环烷酸钕体系催化丙烯酸乙酯及丙烯酸正丁酯的聚合特征。

| Abstract: | The polymerizations of ethyl and butyl acrylates with coordination catalyst: Nd(naph)3-Al(i-Bu)3 were studied. Kinetic studies indicated that both ethyl acrylate polymerization and butyl acrylate polymerization reaction are first order wtih respect to monomer concentration and 0. 5 order to catalyst concentration. The apparent activation energies of EA and BA polymerzation reactions are 17. 8 kJ/mol and 33. 3 kJ/mol respectively. |
