Abstract
The purpose of the present invention is to provide polymerization catalyst which can produce quite efficiently (co)polymer having number average molecular weight and number of molecules which are accurately controlled in producing method of (co)polymer by the polymerization of polar unsaturated compound, and provide living polymerized (co)polymer obtained according to the producing method. For the purpose, polymerization catalyst composition which comprises the composition comprising organic oxysalt compound and hydroxycarbonyl compound having at least both an alcoholic hydroxyl group and a carbonyl group in the same molecule is provided and the polar unsaturated compound is polymerized by using the polymerization catalyst composition. The composition containing the obtained (co)polymer were able to provide thermosetting powder coating composition having particularly excellent characteristics.
