摘　　要：在配位聚合反应的研究中,值得注意的研究课题之一是将稀土催化剂引入到苯乙烯和双烯烃的共聚反应。这一新课题的研究不仅对阐明4f金属配位聚合反应机理,且对开发新型稀土催化剂和共聚物,都有重要意义.例如,共聚物中顺式-1,4含量的多少,对它们的各种性能有明显的影响。A new rare earth catalyst system was found in our laboratory. Not only styrene and iso-prene are copolymerized but also styrene and butadiene are copolymerized with the new catalyst system-4f metal compounds-alkyl aluminium compounds-other components. The copolymers are characterized as the block copolymers containing 4.0-4.5(%) gels, 22.0-97.7(%) cis-l,4-contents and 8.3-79.8 (mol%) styrene contents by means of IR, 1H-NMR,13C-NMR and Dynamic mechanic properties.
