TL;DR: Combinations of dialkylaluminum chlorides and dialkylsmagnesium compounds, when used at molar [AlR2Cl]:[MgR2] ratios ≥ 2, act as universal cocatalysts for all three presently known types of alkene polymerization catalysts (Ziegler-Natta, metallocene, and post-metallocene) as discussed by the authors.
Abstract: Combinations of dialkylaluminum chlorides and dialkylmagnesium compounds, when used at molar [AlR2Cl]:[MgR2] ratios ≥ 2, act as universal cocatalysts for all three presently known types of alkene polymerization catalysts—Ziegler–Natta, metallocene, and post-metallocene. When these cocatalysts are used with supported Ti-based Ziegler–Natta catalysts, they produce catalyst systems which are 1.5–2 times more active than the systems utilizing AlR3 compounds as cocatalysts. Combinations of AlR2Cl/MgR2 cocatalysts and various metallocene complexes produce single-center catalyst systems similar to those formed in the presence of MAO. The same cocatalysts activate numerous post-metallocene Ti complexes containing bidentate ligands of a different nature and produce multicenter systems of very high activity. © 2009 Wiley Periodicals, Inc.

12 Mar 1991TL;DR: In this paper, a phosphorus-containing catalysts for cracking hydrocarbons are described. But the present method is directed to a phosphorus containing catalyst which is formed by spray drying at a pH preferably less than 3.
Abstract: The present invention is directed to a phosphorus containing catalyst which is formed by spray drying at a pH preferably less than 3. The present invention also comprises methods for preparing catalysts comprising phosphoric acid treated clay, as well as methods for cracking hydrocarbons utilizing the novel catalysts disclosed herein. The catalysts of the present invention advantageously exhibit low attritability.

27 Jun 1986TL;DR: In this paper, a layered chalcogenide material of high thermal stability and surface area which contain interspathic polymeric chalinogenides such as polymeric silica is prepared by ion exchanging a layered metal oxide, such as layered titanium oxide, with organic cation, to spread the layers apart.
Abstract: Layered chalcogenide materials of high thermal stability and surface area which contain interspathic polymeric chalcogenides such as polymeric silica are prepared by ion exchanging a layered metal oxide, such as layered titanium oxide, with organic cation, to spread the layers apart. A compound such as tetraethylorthosilicate, capable of forming a polymeric oxide, is thereafter introduced between the layers. The resulting product is treated to form polymeric oxide, e.g. by hydrolysis, to produce the layered oxide material. The resulting product may be employed as catalyst material in the conversion of organic compounds.
