    摘要: A process for producing optically active polyketone which comprises allowing a mono-substituted ethylene to react with carbon monoxide in the presence of a palladium-phosphine complex formed from a phosphine represented by the following general formula (I) ##STR1## (wherein Ar.sup.1 is a phenyl group which may be substituted with one or more substituent groups selected from a lower alkyl group, a lower alkoxy group and a halogen) and a palladium salt. An isotactic (stereoregular) optically active polyketone having high molecular weight (Mn) in which the direction of a mono-substituted ethylene against ketone is a head to tail type (positional regularity) can be produced efficiently by a simple and easy process for the copolymerization of propylene, styrene or the like mono-substituted ethylene with carbon monoxide.
