Abstract:
The present invention generally relates to a new process of making a trialkyl aluminum compound in which at least one alkyl group is a primary alkyl derived from an internal olefin or alpha-olefin. The process employs an isomerization/hydroalumination catalyst.
Abstract:
This invention relates to a asymmetric hydroformylation processes in which a prochiral or chiral olefin is reacted with carbon monoxide and hydrogen in the presence of an optically active metal-ligand complex catalyst to produce an optically active aldehyde or a product derived from an optically active aldehyde.
Abstract:
Methods for producing alpha-olefins. The methods include selectively isomerizing an alpha-olefin to a mixture of beta-olefins and ethenolyzing at least a portion of the mixture of beta-olefins to an alpha-olefin.
Abstract:
The invention generally relates to chain shuttling agents (CSAs), a process of preparing the CSAs, a composition comprising a CSA and a catalyst, a process of preparing the composition, a processes of preparing polyolefins, end functional polyolefins, and telechelic polyolefins with the composition, and the polyolefins, end functional polyolefins, and telechelic polyolefins prepared by the processes.
Abstract:
The invention generally relates to a process for preparing a metal-functionalized polyolefin and a composition useful therein, and to the metal-functionalized polyolefin prepared thereby and new non-metallic polymers prepared therefrom.
