Abstract:
An apparatus for in-situ injection of one or more chemical components into a reaction chamber is disclosed, The apparatus includes a reaction chamber for receiving one or more libraries, each of the libraries comprising two or mor e samples. The reaction chamber is configured to form a sealed enclosure. The apparatus further includes an injection manifold supporting injectors for in - situ injection of one or more chemical components onto respective samples of the one or more libraries in the pressurized sealed reaction chamber.
Abstract:
New ligands, compositions, metal-ligand complexes and arrays with pyridyl-amine ligands are disclosed that catalyze the polymerization of monomers into polymers. 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 polymerizing propylene to high molecular weight isotactic polypropylene in a solution process at a variety of polymerization conditions.

Abstract:
In one embodiment, a parallel batch reactor for effecting chemical reactions includes a vessel block (24) comprising reactor vessels (32) for receiving components of a reaction and a valve block (23) removably attached to the vessel block. The valve block (22) includes a first plurality of valves (72) in fluid communication with an inlet port for supplying pressurized fluid to the reactor vessels. (32) and configured to fluidically isolate one or more of the reactor vessels from (32) at least one of the other reactor vessels (32) The valve block (22) further includes a second plurality of valves (76) in fluid communication with the reactor vessels for injecting chemical components into the pressurized reactor vessels (32) or sampling chemical components from the pressurized reactor vessels (32) The vessel block (26) and valve block (22) are configured to sustain an operating pressure of at least 15 psig. A stirring assembly (26) may also be present.
