Method of producing a cyclized polydiene |
摘要 |
A method of producing a cyclized polydiene comprising cyclizing a polydiene in an organic solvent with the aid of a binary catalyst comprising tin halide or titanium halide and an organosulfonic acid or a haloacetic acid. The method provides a cyclized polydiene having a narrow molecular weight distribution in a short reaction time and with high reproducibility. The method does not entail side reactions causing gelation or discoloration.
