The present invention relates to a carbon monoxide/olefin copolymerizing catalyst, and to a suspension-polymerization production process using same. More particularly, the present invention relates to a compound expressed by chemical formula 1 and comprising an alkyl having a hydrophobic group or an aryl sulfonate anion (RSO 3 n - ), to a carbon monoxide/olefin copolymerizing catalyst using the compound, and to a method for preparing polyketones using the catalyst. When using the catalyst, a carbon monoxide/olefin suspension polymerization can be achieved, and polymer particles can be produced having a high bulk density and in which the shape of the particles can be adjusted to be spherical or granular, thus enabling easy mass production. |
