In this work, copolymerization of two functional monomers, glycidyl methacrylate (GMA) and N , N ‐dimethylaminoethyl methacrylate (DMAEMA), was firstly carried out via reversible addition‐fragmentation chain transfer (RAFT) polymerization successfully. The copolymerization kinetics was investigated under the molar ratio of n [GMA+DMAEMA] 0 / n [AIBN] 0 / n [CPDN] 0 =300/1/3 at 60°C. The copolymerization showed typical "living" features such as first‐order polymerization kinetics, linear increase of molecular weight with monomer conversion and narrow molecular weight distribution. The reactivity ratios of GMA and DMAEMA were calculated by the extended Kelen‐Tüdös linearization methods. The epoxy group of the copolymer PGMA‐ co ‐PDMAEMA remained intact under the conditions of RAFT copolymerization and could easily be post‐modified by ethylenediamine. Moreover, the modified copolymer could be used as a gene carrier.
