    摘要： The invention relates to the production of homopolymers, co-copolymers or block copolymers from cycloolefinic monomer units characterized in that polymerization occurs in the presence of a catalyst of general formula (I), and optionally in the presence of an additive, wherein the substituents and indices have the following meaning: M is a metal from group VIII B of the periodic table of elements; E1, E2 are independently from each other an element from group V A of the periodic table of elements; Z is a bridging structural unit; Ar stands for annelated aryl units independent of each other; L1, L2 stands for formally uncharged Lewis base ligands; X means monovalent or bivalent anions; k means 1 or 2; l, m, n represent 1 or 2, whereby m×n=1.

    摘要翻译： 本发明涉及由环烯类单体单元生产均聚物，共聚物或嵌段共聚物，其特征在于聚合在通式（I）的催化剂存在下进行，并且任选地在添加剂存在下进行，其中取代基和 指数具有以下含义：M是元素周期表第VIIIB族的金属; E1，E2彼此独立地为元素周期表第ⅤA族元素; Z是桥接结构单元; Ar代表彼此独立的芳环单元; L1，L2代表正式不带电的路易斯碱配体; X表示一价或二价阴离子; k表示1或2; l，m，n表示1或2，由此mxn = 1。
