Recyclable solid-supported catalysts for quaternary ammonium iodide-catalyzed living radical polymerization

Quaternary ammonium iodide (R4N+I-) catalysts immobilized on silica particles, Fe3O4 magnetic particles, and organic resin particles were developed for organocatalyzed living radical polymerization. A random copolymer containing the catalytic R4N+I- moieties and the anchoring triethoxysilyl moieties...
