## Abstract A biodegradable block copolymer, poly‐D,L‐lactide (PLA)‐__co__‐poly(ethylene glycol) (PEG), was prepared by the ring‐opening polymerization of lactide with stannous caprylate [Sn(Oct~2~)] as a catalyst; then, the PLA–PEG copolymer was made into nanoparticles by nanoprecipitation under d
