An azido- and bromo-containing compound derived from naturally occurring ethyl cinnamate was usedsuccessfully to prepare block copolymers by a combination of ‘activator generated by electron transfer atom transferradical polymerization’ (AGET ATRP) and Huisgen “click” reactions in emulsion. First, azido-end poly(methyl methacrylate)and alkyne-end polystyrene were prepared under AGET ATRP conditions, then, poly(methyl methacrylate) blockpolystyrene (PMMA-b-PS) diblock copolymer was formed by Huisgen 1,3-dipolar cycloaddition. Finally, polystyreneblock poly(methyl methacrylate) block polystyrene (PS-b-PMMA-b-PS) triblock copolymer was synthesizedvia simultaneous AGET ATRP and click reactions, catalyzed by the same copper-based catalyst. The polymers werecharacterized by 1H nuclear magnetic resonance (NMR) spectroscopy and gel permeation chromatography (GPC),which confirmed the successful synthesis of the corresponding polymers.
