A process for the preparation of co-polymers by reacting carbon monoxide and one or more ethylenically unsaturated compounds under polymerizable conditions in the substantial absence of a liquid non-polymerizable diluent and in the presence of a catalyst system based on
(a) a source of cations of one or more noble metals of Group VIII of the Periodic Table;
(b) a source of anions of acids having a pKa of less than 4;
(c) a source of cations of one of more metals selected from the group consisting of nickel, cobalt, manganese, lead, zinc, magnesium, iron (II), copper (II), lanthanum and neodymium and
(d) a source of bidentate ligands.
一种用于制备共聚物的工艺,该工艺是在基本不存在液态不可聚合稀释剂的情况下,在可聚合的条件下,使一氧化碳和一种或多种乙烯基不饱和化合物发生反应,该催化剂体系的基础是
