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), M1R1R2(R3)m with a compound of formula (II), (R4X)q-(G)*(M2R5R6)g. In formula (I), R1, R2 and R3 are the same or different and represent a hydrogen atom, C1-C20 alkyl, C1-C20 alkyl halide, C6-C20 aryl, C6-C20 aryl halide, C7-C40 arylalkyl, C7-C40 arylalkyl halide, C7-C40 alkylaryl or C7-C40 alkylaryl halide; M1 represents 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 M1 represents an element of the third main group, and m is equal to 0 when M1 represents an element of the second main group. In formula (II), substituents R4X, which contain hetero atoms, is located on a base body G, and: groups R4 are the same or different and represent hydrogen, C1-C20 alkyl, C1-C20 alkyl halide, C6-C20 aryl, C6-C20 aryl halide, C7-C40 arylalkyl, C7-C40 arylalkyl halide, C7-C40 akylaryl or C7-C40 alkylaryl halide; X represents an element of the fourth, fifth or sixth main group of the periodic table of elements; G represents at least bivalent C1-C20 alkylene, C1-C20 alkylene halide, C1-C10 alkylenoxy, C6-C40 arylene, C6-C40 arylene halide, C6-C40 arylenoxy, C7-C40 arylalkylene, C7-C40 arylalkylene halide, C7-C40 alkylarylene, C7-C40 alkylarylene halide; M2 represents an element of the fourth, fifth or sixth main group of the periodic table of elements; R5 and R6, independent of one another, are the same or different and represent a hydrogen atom, C1-C20 alkyl, C1-C10 alkoxy, C2-C10 alkenyl, C7-C20 arylalkyl, C7-C20 alkylaryl, C6-C10 aryloxy, C1-C10 alkyl 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.
