摘要: ABSTRACTPolycaprolactone with azide (PCL-N3) and polyethylene glycol α,β-unsaturated ester (maPEG) as chain-end functional group were synthesized, respectively. Then, facile synthesis of polycaprolactone-block-polyethylene (PCL-b-PEG) amphiphilic copolymer by azide-zwitterion cycloaddition PCL-N3 maPEG, the first example, was reported. The self-assembly this carried out in deionized water, then formation vesicles proven result transmission electron microscope (TEM). Grainsize analyzer suggested that diameter is 305 nm average polydispersity 0.128. provides a powerful method for post-functionalization or end-functionalized polymers.
