Abstract:
New ligands, compositions, metal-ligand complexes and arrays with pyridylamine ligands are disclosed that catalyze the polymerization of monomers into polymers. Processes for polymerisation and polymers are further illustrated. Certain of these catalysts with hafnium metal centers have high performance characteristics, including higher comonomer incorporation into ethylene/olefin copolymers, where such olefins are for example 1-octene, isobutylene or styrene. Certain of the catalysts are particularly effective at polymerising propylene to high molecular weight isotactic polypropylene in a solution process at a variety of polymerisation conditions.
Abstract:
Methodologies for the synthesis, screening and characterisation of organometallic compounds and catalysts (eg homogenous catalysts), including combinatorial synthesis, screening and characterisation of libraries of supported and unsupported organometallic compounds and catalysts (eg homogenous catalysts). The methods can be applied to the preparation and screening of large numbers of organometallic compounds which can be used not only as catalysts (eg homogeneous catalysts), but also as additives and therapeutic agents.

Abstract:
A method of preparing and delivering a slurry into a series of vessels in a reactor, said method comprising: (1) mixing a particulate solid material and a liquid dispersing medium and agitating the mixture to form a substantially homogeneous first slurry in which said particulate solid material is suspended in the liquid; (2) aspirating said first slurry into a cannula carried by a robot system while the slurry is substantially homogeneous; (3) operating the robot system to insert the cannula into the reactor;(4) delivering the slurry from the cannula into the vessel while the cannula is in said reactor; and (5) repeating (2)-(4) for a second vessel with said first slurry or repeating (2)-(4) for a second vessel with a second slurry.
Abstract:
A parallel reactor system including a reactor and vessels in the reactor for holding reaction mixtures, and a cannula for introducing fluid reaction material into the vessels. A robot system is operable to insert the cannula into cannula passages in the reactor for delivery of reaction materials, including slurries, to respective vessels, and to withdraw the cannula from the cannula passages after delivery. Related methods and cannula designs are also disclosed.

Abstract:
The present invention relates, inter alia, to methodologies for the synthesis, screening and characterization of organometallic compounds and catalysts (e.g. homogeneous catalysts). The methods of the present invention provide for the combinatorial synthesis, screening and characterization of libraries of supported and unsupported organometallic compounds and catalysts (e.g. homogeneous catalysts). The methods of the present invention can be applied to the preparation and screening of large numbers of organometallic compounds which can be used not only as catalysts (homogeneous catalysts), but also as additives and therapeutic agents.
