| 摘要 |
A novel catalyst composition containing a palladium salt, an anion of a non-hydrohalogenic acid with a pka of less than 2, a phosphorus bidentate ligand and an acid with a pka of at least 4 but less than 6. The catalyst composition effectively polymerizes carbon monoxide and at least one ethylenically unsaturated hydrocarbon to produce linear, alternating polymers.
