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:
Catalysts comprising Salan ligands with bridged or unbridged diphenyl amine moieties. Also, catalyst systems comprising the catalyst and an activator; methods to prepare the ligands, catalysts and catalyst systems; processes to polymerize olefins using the catalysts and/or catalyst systems; and the olefin polymers prepared according to the processes.
摘要:
Disclosed herein are polyalphaolefins and Salan cataylsts, catalyst systems, and processes to produce the polyalphaolefins. The salan catalysts of the invention are applied as unitary compounds with the activators built in the conjugate ring structure, wrapping around a Group IV metal. The method allows production of highly steroregular products with narrow distribution of molecular masses of the growing polymer chains.
