Patent number: 5519101Abstract: 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.Type: GrantFiled: May 27, 1993Date of Patent: May 21, 1996Assignee: Amoco CorporationInventors: Philip O. Nubel, Vahid Bagheri
