    摘要： This invention is directed to a process for the preparation of polyolefins from one or more olefinic monomers comprising combining said olefins under olefin polymerization conditions with an organometallic catalyst compound that is activated for olefin polymerization by reaction with at least one Lewis acid aluminum compound of the formula RnAl(ArHal)3−n, where “ArHal” is a halogenated aryl group, n=1 or 2, and R is a monoanionic group other than a halogenated aryl group. The invention also relates to a polymer produced using the process and to the polymer itself.

    摘要： 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 compound with a diol. The activator compound is represented in one aspect by: wherein each M1 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 of 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.
