Chemical products suited for use as co-catalysts, method for the preparation thereof and their use in catalyst systems for producing polyolefins

Abstract

The invention relates to chemical products which are suited for use as co-catalysts and which can be obtained by reacting a compound of formula (I), MRR(R)with a compound of formula (II), (RX)-(G)*(MRR). In formula (I), R, Rand Rare the same or different and represent a hydrogen atom, C–Calkyl, C–Calkyl halide, C–Caryl, C–Caryl halide, C–Carylalkyl, C–Carylalkyl halide, C–Calkylaryl or C–Calkylaryl halide; Mrepresents an element of the second or third main group of the periodic table of elements, and; m equals 0 or 1, whereby m is equal to 1 when Mrepresents an element of the third main group, and m is equal to 0 when Mrepresents an element of the second main group. In formula (II), substituents RX, which contain hetero atoms, is located on a base body G, and: groups Rare the same or different and represent hydrogen, C–Calkyl, C–Calkyl halide, C–Caryl, C–Caryl halide, C–Carylalkyl, C–Carylalkyl halide, C–Cakylaryl or C–Calkylaryl halide; X represents an element of the fourth, fifth or sixth main group of the periodic table of elements; G represents at least bivalent C–Calkylene, C–Calkylene halide, C–Calkylenoxy, C–Carylene, C–Carylene halide, C–Carylenoxy, C–Carylalkylene, C–Carylalkylene halide, C–Calkylarylene, C–Calkylarylene halide; Mrepresents an element of the fourth, fifth or sixth main group of the periodic table of elements; Rand R, independent of one another, are the same or different and represent a hydrogen atom, C–Calkyl, C–Calkoxy, C–Calkenyl, C–Carylalkyl, C–Calkylaryl, C–Caryloxy, C–Calkyl halide; q is a whole number ranging from 2 to 100, and; g is a whole number ranging from 1 to 100. The invention also relates to a method for preparing the inventive chemical products, and to their use in catalyst systems for producing polyolefins.
