  • Patent number: 6043401
    Abstract: Catalysts and processes are described to make low molecular weight, essentially terminally-unsaturated, viscous poly(1-olefin) or copoly(1-olefin) having a high terminal vinylidine content from a feed stock containing one or more 1-olefin and other volatile hydrocarbon liquids using a Ziegler catalyst made from a Group IVb metallocene and an aluminoxane cocatalyst, particularly bis(cyclopentadienyl) and bis(indenyl) titanium(IV), zirconium(IV) or hafnium(IV) compounds and methylaluminoxane. A particularly useful feed stock is a refinery stream containing 1-olefins and isobutylene which is used to make polyisobutylene.

  • Patent number: 5519101
    Abstract: A polymerization process for preparation of oligomers and polymers having at least one internal carbon-to-carbon double bond and containing functional groups comprising terminal carbon-to-carbon double bonds is disclosed. The polymerization process is substantially free of side reactions comprising double bond migration. The oligomers and polymers are prepared from acyclic polyenes of from 2 to about 30 carbon atoms. The catalyst system comprises a metathesis catalyst (A) comprising a transition metal compound, an activator (B) selected from the group consisting of organic tin compounds and organic aluminum halides and (C) an organic Lewis base. Yields are at least 60% of theoretical based on acyclic polyene reactant.
