摘要: An ethylene oligomerization catalyst that oligmerizes ethylene to a series of α-olefins and that has a Schulz-Flory constant of about 0.75 to 0.995 produces a stream of α-olefins. This stream is then added to a vessel containing ethylene and a copolymerization catalyst that copolymerizes ethylene and α-olefins. The resulting branched polyethylene often has good processing properties. The good processing is presumably due to the presence of “long chain branching”. Such polymers are useful for films and other packaging materials, and for molding resins for molding parts such as industrial, automotive or electrical parts.

摘要: Mixtures of different polyolefins may be made by direct, preferably simultaneous, polymerization of one or more polymerizable olefins using two or more transition metal containing active polymerization catalyst systems, at least one of which contains cobalt or iron complexed with selected ligands. The polyolefin products may have polymers that vary in molecular weight, molecular weight distribution, crystallinity, or other factors, and are useful as molding resins and for films.

摘要: Polyolefins, especially branched polyethylenes, can be made by combining a catalyst that can oligomerize ethylene to one or more alpha-olefins and a polymerization catalyst which can copolymerize ethylene and &agr;-olefins, by first carrying out the process in, for example, a continuous stirred tank reactor or its equivalent, and then in a plug flow reactor or its equivalent. The process minimizes the occurrence of (unreacted) &agr;-olefins in the final polymer product.
