摘要：
Non-cross-linked chloromethyl polystyrene (NCPS) with high loading and excellent solubility has been effectively and facilely prepared using radical copolymerization of styrene and p-chloromethyl styrene under microwave irradiation. The NCPS supported quaternary ammonium salts have also been prepared by two different methods: chemical modification reactions on NCPS and one-pot reaction of St, CMS and TBA. The catalysts coupled the advantages of conventional solution phase catalysts and insoluble polymer-supported catalysts, catalyzed some nucleophilic substitution reactions under phase transfer catalysis condition effectively under microwave irradiation.
