Abstract

PURPOSE: The title stable copolymerization catalyst easily separable from the reaction product, having a high copolymerization activity, comprising an organic compound of a metal of Groups IIWIII in the periodic table supported on a high polymer chain.
CONSTITUTION: (A) An organic compound of a metal of Groups IIWIII in the periodic table, e.g., an alkyl or aralkyl derivative of Zn, Mg, or Al, and (B) a high polymer having functional groups which can coordinate with the compound (A) and are partly modified are mixed in a solvent, and the resulting product or coordination complex is aged in the atmosphere of carbon dioxide under pressure to give the desired catalyst. Polyhydroxystyrene having partly modified hydroxyl groups or polyacrylic acid having partly modified carboxyl groups may be cited as the high polymer.
