A process for preparing a polymer by using a copper compound which is easy to synthesize and is stable as a polymerization catalyst. The process is characterized in that a vinyl monomer having a polar value e of not more than 1.5 in terms of absolute value is polymerized by using as a catalyst and/or a polymerization initiator a copper compound represented by the general formula CuXn, LCuXn, or L(L')CuXn (wherein L and L' represent each a ligand; X represents a halogen atom or an alkoxy, thioxy, allyloxy, amino, secondary amino, tertiary amino, cyano, nitro, alkyl, or allyl group; and n is an integer of 0 to 2).
La présente invention concerne un procédé de préparation d'un polymère en utilisant un composé du cuivre facile à synthétiser et stable comme catalyseur de polymérisation. Le procédé est caractérisé en ce qu'un monomère de vinyl dont la valeur polaire (e) n'excède pas 1,5 en valeur absolue est polymérisé en utilisant comme catalyseur et/ou comme amorceur de polymérisation un composé du cuivre représenté par la formule générale CuXn, LCuXn, ou L(L')CuXn dans laquelle L et L' représentent chacun un ligand, X représente un atome halogène ou un groupe alcoxy, thioxy, allyloxy, amino, amino secondaire, amino tertiaire, cyano, nitro, alkyl ou allyl, et n est un entier valant 0, 1 ou 2.
