Strongly acid cation exchangers with improved properties are obtained if the sulphonation of the non-functionalized polymers is carried out at a high temperature and/or in the absence of oxygen.

Сильно кисловочные обменники катиона с улучшенными свойствами получены если сульфуризация non-functionalized полимеры снесена вне на высокую температуру and/or в отсутствие кислорода.
