Summary
The title materials are produced from macroporous styrene (St)-divinylbenzene (DVB) resins prepared in the presence of a polymer solution as a porogen; the resulting beads are functionalized upon grafting St-Vinylbenzylchloride (VBC) copolymers through post-copolymerization with residual double bonds. The resulting material has been quaternized by trimethylamine at 35° C. The rate constant of that reaction is then about 6 times higher than that observed for a similar resin (same Cl content and same porous morphology) prepared by direct terpolymerization of St, DVB and VBC.
