CYCLIC OLEFINIC POLYMER WITH REDUCED CONTENT OF REMAINING CATALYST, USE OF SUCH A POLYMER AND PROCESS FOR PRODUCING THE SAME |
| abstract |
A cycloolefin polymer reduced in the content of catalyst residues; and use thereof as an optical material. The catalyst used in polymerization and/or hydrogenation for producing a cycloolefin polymer is efficiently decomposed by adding at least one compound selected from the group consisting of α-hydroxy acids and β-hydroxy acids each having one hydroxyl group and one carboxyl group in the molecule and their derivatives in each of which the hydroxyl group has been replaced with an alkoxyl group. The decomposition products are insolubilized in the reaction solvent used in the polymerization and/or hydrogenation and are thus efficiently precipitated and removed. |
