    • The present invention relates to a method for the production of an ethylene/propylene/diene copolymer by means of solution polymerization, and more specifically one for a copolymer whose main components are ethylene, propylene and diene monomers using a catalyst of a transition metal coordination compound; the constituent components and characteristics of the copolymer being as follows. The catalyst composition provided by the present invention, which is used to produce a copolymer of which (a) the ethylene content is from 30 wt. % to 80 wt. %, (b) the propylene content is from 19.9% to 60 wt. % and (c) the diene content is from more than 0 wt. % to 15 wt. %, comprises a catalyst system using an activating agent of a compound of aluminum or boron, or aluminoxane together with a transition metal catalyst comprising at least one anionic ligand having an aryloxy group substituted with an aryl derivative in the ortho position and a cyclopentadiene derivative, and provides a highly active polymerization method with outstanding reactivity with respect to ethylene, propylene and diene compounds.
    • 本发明涉及一种通过溶液聚合制备乙烯/丙烯/二烯共聚物的方法,更具体地说,涉及使用过渡金属配位化合物的催化剂的主要成分为乙烯,丙烯和二烯单体的共聚物的方法 ; 共聚物的组成成分和特性如下。 由本发明提供的催化剂组合物,其用于制备共聚物,其中(a)乙烯含量为30重量% %至80wt。 %,(b)丙烯含量为19.9%至60wt。 %和(c)二烯含量大于0wt。 %至15wt。 %,包括使用铝或硼化合物的活化剂或铝氧烷的催化剂体系以及包含至少一个在邻位被芳基衍生物取代的芳氧基的阴离子配体和环戊二烯衍生物的过渡金属催化剂, 并提供了对乙烯,丙烯和二烯化合物具有突出反应性的高活性聚合方法。
