The invention relates to a method for oligomerizing olefins according to which an olefin is brought into contact with a catalyst system comprising: a) at least one transition metal complex having a multidentate complex ligand, and; b) an alkylalumoxane in quantities in which the molar ratio of aluminum to transition metal is greater than 10, whereby at least one portion of the quantity of the transition complex is added continuously or in portions over the course of oligomerization. The method enables the production of greater quantities of olefin oligomers with a given quantity of alkylalumoxane.
本发明涉及一种寡聚烯烃的方法,根据该方法,将烯烃与催化剂体系接触,该催化剂体系包括:a)至少一种具有多配位
配体的过渡
金属络合物;b)一种烷基铝氧烷,其中铝与过渡
金属的摩尔比大于10,至少部分过渡
金属络合物的数量在寡聚化过程中连续或分批添加。该方法使得在给定数量的烷基铝氧烷的情况下,可以生产更多量的烯烃寡聚物。
