    • 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.
    • 一种制备光学活性聚酮的方法,其包括在由以下通式(I)表示的膦形成的钯 - 膦配合物的存在下使单取代的乙烯与一氧化碳反应(其中 Ar 1是可以被一个或多个选自低级烷基,低级烷氧基和卤素的取代基取代的苯基)和钯盐。 具有高分子量(Mn)的全同立构(有规立构)光学活性聚酮,其中单取代的乙烯对酮的方向是头 - 尾型(位置规则性)可以通过简单和容易的共聚方法有效地制备 丙烯,苯乙烯等单取代乙烯与一氧化碳。
