Abstract
Contacting carbon monoxide, at lease one .alpha.-olefin, and at least one conjugated diene in the presence of a catalyst composition formed by contacting a palladium compound, the anion of an acid having a pKa less than 6 and a bidentate phosphorus or nitrogen ligand results in the production of novel polyketone terpolymers.

The process of producing a linear, alternating polymer by polymerizing carbon monoxide, at least one .alpha.-olefin, and at least one conjugated diene, in the presence of a catalyst composition formed by contacting a palladium compound, the anion of an acid having a pKa less than 6, and a bidentate ligand of phosphorus or nitrogen.
Linear alternating polymer of carbon monoxide with other monomers, said polymer having olefinically unsaturated double bonds promoting crosslinking or further chemical modification by addition reactions at the double bonds and consisting essentially of:
- first units of the formula --(C.dbd.O)--(A)-- wherein A is a polymer unit which derives from one or more alpha-olefins;
- second units of the formula --(C.dbd.O)--(B)-- where B is a polymer unit having a mono-olefinically unsaturated functional group which derives from one or more conjugated dienes;
- and
- the first and second units being randomly distributed with fewer than 1000 of the first units being present on the average for each second unit that is present.
