Process for producing polyketone |
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 wherein an organometallic complex comprising acetate-palladium and 1,3-bis[bis(2-methoxy-5-methylphenyl)phosphino]propane is used as a catalyst component, and a mixed solvent of 70 to 90 vol % of acetic acid and 10 to 30 vol % of water is used as a liquid medium. |
