Patent

CA 2466907

The present invention includes polymerization catalyst activator complexes which include at least Group 13 metals. The activator complexes of the invention are prepared, in general, by reacting a halogenated aryl Group 13 metal compoudn with a diol. The activaor compound is represented in one aspect by Formula (I) wherein each Mi is a Group 13 atom; each R3, R3', R3'', and R3''' group is independently selected from, for example, C1 to C30 alkyls, halogenated C1 to C30 alkyls, C6 to C60 halogenated aryls; with the proviso that at least one R3, R3' R3'', and R3''' is a fluorinated C6 to C60 aryl group; R1 and R2 are independently selected from substituted or unsubstituted C1 to C100 hydrocarbylenes; R, when present, is a substituted or unsubstituted C30 hydrocarbylene; wherein when R is absent, R1 and R2 are bound together; and x is 0 or an integer from 1 to 100.

L'invention porte sur des complexes activateurs de catalyseurs de polymérisation comportant au moins des métaux du groupe 13, et qui sont préparés, en général, en faisant réagir un composé "aryle halogéné/métal du groupe 13" avec un diol. Lesdits complexes activateurs sont représentés dans l'un de leurs aspects par la formule (I) dans laquelle: chaque M?i¿ est un atome du groupe 13; chaque groupe R?3¿, R?3'¿, R?3''¿, et R?3'''¿ est indépendamment choisi par exemple parmi des alkyles C¿1? à C¿30?, des alkyles halogénés C¿1? à C¿30?, et des aryles halogénés C¿6? à C¿60?, sous réserve: qu'au moins un R?3¿, R?3'¿ R¿3''¿, et R?3'''¿ soit un groupe aryle C¿6? à C¿60? fluoré; que R?1¿ et R?2¿ soient indépendamment choisis parmi des hydrocarbylènes C?1¿ à C?100¿ substitués ou non; que R, si présent, soit un hydrocarbylène C?30¿, et que, si R est absent, R?1¿ et R?2¿ soient liés ensemble; et x est 0 ou un entier de 1 à 100.
