ABSTRACT:
A cyclic olefin having a specific polar group is polymerized by addition polymerization in a hydrocarbon solvent, using a polymerization catalyst component containing (i) a specific transition metal compound, (ii) a Lewis acid compound and (iii) an alkyl aluminoxane, or the cyclic olefin is polymerized by addition polymerization in the hydrocarbon solvent, using the polymerization catalyst component, by further adding at least one aromatic vinyl compound and at least one cyclic nonconjugated polyene compound, or either one of them as a molecular weight modifier, thereby obtaining a cyclic olefinic addition polymer.
