Abstract
Novel polymers containing alternating units of carbon monoxide and units derived from non-conjugated diolefinic hydrocarbon are produced by contacting the carbon monoxide and non-conjugated diolefinic hydrocarbon under polymerization conditions in the presence of a catalyst composition formed from a compound of palladium, the anion of a strong non-hydrohalogenic acid and a bidentate ligand of phosphorus having only aliphatic monovalent phosphorus substituents.
Claims18
A process for the production of a polymer having alternating units of carbon monoxide and units derived from at least one non-conjugated diolefinic hydrocarbon which comprises contacting carbon monoxide and non-conjugated diolefinic hydrocarbon under polymerization conditions in the presence of a liquid reaction diluent and a catalytic quantity of a catalyst composition formed from a compound of palladium, the anion of a strong non-hydrohalogenic acid and a bidentate ligand of phosphorus wherein each monovalent phosphorus substituent is aliphatic.
The process of claim wherein the bidentate phosphorus ligand is represented by the formula ##STR3## wherein R independently is aliphatic of up to 10 carbon atoms inclusive and R' is a divalent hydrocarbon bridging group of up to 10 carbon atoms inclusive with from 2 to 4 carbon atoms in the bridge.
