| 摘要 |
A process for the preparation of a strong acid cation exchange material (I) by the sulphonation of a crosslinked styrene polymer is claimed. The sulphonation is carried out at 125-150 degrees C in the presence or absence of oxygen. (I) with a conductivity of less than 50 microS/cm is also claimed. |
