摘要 |
<p>The invention relates to sulphonated polymer resins, particularly polymer resins with a sulphonated shell layer, and the preparation thereof. Resins according to the invention are prepared by sulphonating a polymer in a non-swollen state with substantially pure gaseous sulphur trioxide substantially in the shell layer of the polymer particles. The polymer to be sulphonated can be for example a styrene-DVB copolymer. The resins according to the invention can be used for example as chromatographic resins, ion-exchange resins and catalyst resins.</p> |
