| 摘要 |
Ion-exchange resin having at least one thiol functional group obtainable by reacting crosslinked bead polymers of acrylic compounds, and aminothiols, is claimed. An independent claim is also included for preparing the ion-exchange resin having thiol functional groups, comprising (a) reacting an organic phase containing monomer droplets of at least one acrylic compound, at least one multifunctional ethylenically unsaturated compound, optionally at least one porogen and/or optionally an initiator or an initiator combination, in an aqueous phase to obtain a crosslinked bead polymer, and (b) reacting the crosslinked bead polymer with at least one aminothiol by adding it to the aqueous phase, or by filtering, decanting or centrifuging the bead polymers obtained from (a) after intermediate isolation, re-suspending it in an aqueous phase, and adding the aminothiol. |
