Abstract

Summary: Stepwise anionic polymerization, catalytic hydrogenation, and atom transfer radical polymerization were performed to synthesize an amphiphilic ABC triblock copolymer, poly(ethylene-alt-propylene)-block-poly(ethylene oxide)-block-poly(hexyl methacrylate) (PEP-b-PEO-b-PHMA), with hydrophilic PEO as the middle block. The resulting block copolymers have well-defined molecular weights and narrow molecular weight distributions as revealed by 1H NMR spectroscopy and gel permeation chromatography.
