摘 要：
PROBLEM TO BE SOLVED: To provide a method for efficiently and inexpensively producing a high-molecular-weight polyketone polymer.;SOLUTION: The method for producing the high-viscosity polyketone is one comprising
copolymerizing carbon monoxide with at least one ethylenically unsaturated compound in the presence of a metal complex catalyst obtained by reacting a palladium compound with a bidentate ligand having a group 15 atom and an anion of an acid of a pKa of 4 or below to produce a polyketone having an intrinsic viscosity of 2.5 dL/g or above, wherein isopropanol is used as a reaction medium or an additive.;COPYRIGHT: (C)2004,JPO 主权项：
パラジウム化合物と、第１５族元素の原子を有する二座配位子と、ｐＫａが４以下の酸の陰イオンとを反応させることによって得られる金属錯体触媒の存在下で、一酸化炭素とエチレン性不飽和化合物の１種若しくは２種以
