METHOD FOR REDUCING THE OLIGOMERIC CYCLIC ETHER CONTENT OF A POLYMERIZATE |
| 摘要 |
The oligomeric cyclic ether content of a tetrahydrofuran/alkylene oxide polymerizate is significantly reduced by bringing the polymerizate into contact at elevated temperatures with an ion exchange resin bearing -SO3H groups. |
