摘要： A single-site olefin polymerization catalyst and method of making it are disclosed. The catalyst comprises an activator and an organometallic complex. The complex comprises a Group 3 to 10 transition or lanthanide metal, M, and at least one chelating N-oxide ligand that is bonded to M. Molecular modeling results indicate that single-site catalysts based on certain chelating N-oxide ligands (e.g., 2-hydroxypyridine) will rival the performance of catalysts based on cyclopentadienyl and substituted cyclopentadienyl ligands.

摘要： Olefin polymerization in the presence of heterogeneous supported catalysts is improved by incorporating into the supported catalyst a unifunctional hydrophobic tether comprising a hydrophobic portion containing no basic nitrogen and a univalent reactive group. The unifunctional hydrophobic tether reduces fouling and sheeting in gas phase polymerization processes and improves polymer morphology and bulk density in slurry polymerization processes, while substantially maintaining or enhancing catalyst polymerization activity.

摘要： Multimodal polyolefin polymers may be prepared in series-connected polymerization reactors where a prior reactor is a slurry reactor employing light solvent as the slurry medium and hydrogen to limit polymer molecular weight, the polymer product from the prior reactor being substantially freed of hydrogen prior to entry into a subsequent polymerization reactor operating at low hydrogen pressure to produce a high molecular weight olefin. The economics and operating performance of such a series slurry reactor polyethylene process can be significantly improved through the use of an intermediate slurry transfer system and hydrogen removal apparatus that employs flash drums in series in conjunction with a warm recycle solvent slurry diluent.

摘要： An injection pump assembly 10 in a chemical delivery system for simultaneously delivering reagents into a combinatorial reactor system having multiple injectors. The assembly 10 has a plurality of injectors 12, each injector 12 being in fluid communication with one of the multiple reactors. Each injector 12 has (1) a pump 14 in which a plunger 18 sealingly moves to ingest, store and discharge a flushing solvent 20; (2) a pipette assembly 22 for loading, storing, and discharging one or more reagents into one of the reactors in the combinatorial reactor system, first and second reservoirs for retaining some of the reagents; (3) one or more hollow needles 32, each for selectively delivering a reagent 24 to the first 28 or the second 24 reservoir; (4) a first valve 34 positioned downstream of the first 28 reservoir; and (5) a second valve 36 positioned downstream of the second 30 reservoir. When each valve 34, 36 is in a closed position, the reagents 24, 48 can be stored in isolation from each other. When each valve 34, 36 is in an open position, the reagents 24, 48 may flow through the pipette assembly 22. A 3-way valve 38 is positioned between the pump 14 and the pipette assembly 22. An actuator assembly 46 is in operable communication with each of the plurality of injectors so that the 3-way valves 38 of each injector may be repositioned in unison, thereby delivering precise amounts of the flushing solvent 20 and the reagents 24, 48 in varied or consistent amounts to each reactor in the combinatorial reactor system. The inventive method involves operation of the disclosed injection pump assembly.

摘要： Single-site catalysts useful for polymerizing olefins are disclosed. The organometallic catalysts incorporate a Group 3 to 10 transition, lanthanide or actinide metal and a caged diimide ligand. The diimide ligands are made by a tandem Diels-Alder and photochemical null2null2null cycloaddition sequence to give a multicyclic dione, followed by condensation with a primary amine. Because a wide variety of caged diimide ligands are easy to prepare from commercially available dienes and dienophiles, the invention enables the preparation of a new family of single-site catalysts. Based on their unique structure and geometry, the catalysts offer polyolefin producers new ways to improve activity, control comonomer incorporation, or regulate polyolefin tacticity.
