Amphipathic ethylene glycol-butadiene block copolymers (PEG-PB) with different chain lengths of poly(ethylene glycol) (PEG) were synthesized by reacting poly(ethylene glycol methyl ether) (m-PEG, mol. wt = 350, 550, 750, 2000 and 5000) with telechelic polybutadiene (PB). The PEG-PB copolymers formed
