Abstract: The present invention relates to a catalyst composition for the polymerisation of olefins comprising a support containing a single site catalyst component, a catalyst activator and a modifier wherein the modifier is the product of reacting an aluminum compound of general formula AI(R1, R2, R3) with an amine compound of general formula N(R4, R5, R6). The catalyst composition reduces fouling and/or sheeting when used to catalyse the polymerisation of olefins. The present invention also relates to a method for the polymerisation of olefins using the catalyst composition of the invention.
Abstract translation: 本发明涉及一种用于烯烃聚合的催化剂组合物，其包含含有单中心催化剂组分，催化剂活化剂和改性剂的载体，其中改性剂是使通式AI的铝化合物（R1，R2，R3 ）与通式为N（R4，R5，R6）的胺化合物反应。 催化剂组合物当用于催化烯烃的聚合时减少结垢和/或片材。 本发明还涉及使用本发明的催化剂组合物使烯烃聚合的方法。
