## Abstract Graft copolymers of poly(ethylene glycol) (PEG) on a chitosan backbone (PEG‐g‐chitosan) have been synthesized and their aqueous solution properties were investigated. At pH 6.5 the graft copolymers are 100% soluble, while chitosan phase separates from solution at those conditions. These
## Abstract A novel synthetic approach to biodegradable amphiphilic copolymers based on poly (ϵ‐caprolactone) (PCL) and chitosan was presented, and the prepared copolymers were used to prepare nanoparticles successfully. The PCL‐graft‐chitosan copolymers were synthesized by coupling the hydroxyl en
