Catalytic, diluent preparation of poly ketone having unsaturated terminal group |
| abstract |
Contacting carbon monoxide and at lease one α-olefin in a diluent comprising at least 50% by volume of an aprotic polar compound in the presence of a catalyst formed by contacting a palladium compound, the anion of an acid having a pKa less than 4 and a bidentate phosphorus ligand results in the production of novel polyketone polymers having unsaturated end groups. |
