摘要： This invention relates to organoaluminum compounds, organoaluminum activator systems, preferably supported, to polymerization catalyst systems containing these activator systems, and to polymerization processes utilizing the same. In particular, this invention relates to catalyst systems comprising ion-exchange layered silicate, a catalyst compound, an activator and an aluminum compound represented by formula: Al(R′)3−v(R″)v, wherein each R′, independently, is a C1-C30 hydrocarbyl group; each R″, independently, is a C4-C20 hydrocarbenyl group; and v is from 0.1 to 3.

摘要： New pyridylamide transition metal complex compositions for olefin polymerizations are described herein featuring a 7-membered chelate ring and a cyclometalated hydrocarbyl group. When activated using typical activators these compositions form active alkene polymerization catalysts. Theses novel catalyst compositions are shown herein to be active for olefin polymerization, especially for preparation of polymers containing ethylene.
