Abstract:
The present invention relates to a process for preparing polyketone with improved catalytic activity and intrinsic viscosity, and specifically a process for preparing polyketone, using a mixed solvent of 40 to 60 mol % acetic acid and 40 to 60 mol % water, as a liquid medium, and the precursor of palladium chloride-1,3-bis[di(methoxyphenyl)phosphino]propane, as a catalyst component.
