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:
New ligands and compositions with bridged bis-aromatic ligands are disclosed that catalyze the polymerization of monomers into polymers. These catalysts with metal centers have high performance characteristics, including higher comonomer incorporation into ethylene/olefin copolymers, where such olefins are for example, 1-octene, propylene or styrene. The catalysts also polymerize propylene into isotactic polypropylene.

New ligands, compositions, metal-ligand complexes and arrays with bridged bi s- aromatic ligands are disclosed that catalyze the polymerization of monomers into polymers. These catalysts with metal centers have high performance characteristics, including higher comonomer incorporation into ethylene/olef in copolymers, where such olefins are for example, 1-octene, propylene or styrene. The catalysts also polymerize propylene into isotactic polypropylen e.

Abstract:
Ligands, compositions, and metal-ligand complexes that incorporate heterocycle-amine compounds are disclosed that are useful in the catalysis of transformations such as the polymerization of monomers into polymers. The catalysts have high performance characteristics, including higher comonomer incorporation into ethylene/olefin copolymers, where such olefins are for example, 1-octene, propylene or styrene. The catalysts also polymerize propylene to form isotactic polypropylene.
