Abstract
A process for the synthesis of a catalyst for the polymerization of carbon monoxide and at least one olefin which comprises treating a mixture of a compound of palladium, such as tetrakis(acetonitrile) palladium, and a Lewis acid anion, such as a fluoride of a metal selected from Group III to Group V of the Periodic Table (e.g., boron trifluoride), with carbon monoxide and an olefin followed by reaction of the resulting composition with a bidentate ligand reagent, such as a 1,3-bis(diphenyl-phosphino) alkane (e.g., 1,3-bis(diphenyl-phosphino) propane).
Claims18
A process for the synthesis of a catalyst for the polymerization of carbon monoxide and at least one olefin which comprises treating a mixture of a compound of palladium and an anion, which is effective in the catalyst for such polymerization, with carbon monoxide and an olefin followed by reaction of the resulting composition with a bidentate ligand reagent.
A process for the polymerization of carbon monoxide and at least one olefin which comprises the use of a catalyst, which comprises a compound of palladium, a bidentate ligand reagent, and an anion, which is effective in the catalyst for such polymerization, said catalyst being formed by treating the compound of palladium and the anion of the acid with carbon monoxide and an olefin followed by reaction of the resulting composition with a bidentate ligand reagent.
