    • A process for the preparation of copolymers of carbon monoxide with an olefinically unsaturated compound comprising copolymerizing the monomers in the presence of a catalyst composition based upon (a) a salt of a Group VIII metal, and (b) a cation which is selected from cationic oxidants and cations of the general formulae R.sub.n H.sub.4-n N.sup.+, R.sub.m H.sub.3-m C.sup.+ and R.sub.m H.sub.3-m O.sup.+, wherein n is 0, 1, 2, 3 or 4, m is 2 or 3, and R represents a hydrocarbyl group and/or two or three of R together with the atom carrying a positive charge represent a ring structure, on the understanding that when n is 3, at most two of R together with nitrogen represent a heterocyclic ring structure, and when n is 4, three of R together with nitrogen represent an aromatic heterocyclic ring structure.
    • 一种制备一氧化碳与烯属不饱和化合物的共聚物的方法,包括在催化剂组合物的存在下,基于(a)第Ⅷ族金属的盐和(b)选自阳离子 氧化剂和通式为RnH4-nN +,RmH3-mC +和RmH3-mO +的阳离子,其中n为0,1,2,3或4,m为2或3,R为烃基和/或两个或三个 的R原子与带正电荷的原子一起表示环结构,应当理解,当n为3时,R中最多两个与氮一起表示杂环结构,当n为4时,R中的三个与氮一起 表示芳族杂环结构。
