PtBA-g-PPEGMEMA amphiphilic graft copolymer,consisting of poly(tert-butylacrylate)back- bone and poly(poly(ethylene glycol)methyl ether methacrylate)side chains,was synthesized by the combi- nation of reversible addition-fragmentation chain transfer(RAFT)polymerization and atom transfer radical polymerization(ATRP).The limitation of low and uncontrolled grafting density while introducing the grafting points onto the polymer backbone by polymer post-modification can be overcome by this strategy.The anti-cancer drug,doxorubicin (DOX),was loaded using PtBA-g-PPEGMEMA as the carrier to get a DOX-loaded micelle-based nano-carrier with a Dh around 164.8nm.Drug release experiment of the nano-carrier indicated the delayed drug release characteristics.

Key words: amphiphilic graft copolymer, RAFT, ATRP, drug carrier
