Macro‐azo‐initiators (MAIs) having poly(ethylene glycol) (PEG) units were obtained by various multistep synthetic approaches. In the first stage, macro‐azo‐initiators of PEG type with azo groups inserted in the main chain were prepared. MAIs were then characterized by chemical analyses, spectral methods, 1 H‐NMR, GPC, and DSC techniques. They were used in the free‐radical bulk polymerization of dicyclohexylitaconate to synthesize AB block copolymers of poly(ethylene glycol‐ b ‐dicyclohexylitaconate) (PEG‐ b ‐PDCHI). © 1997 John Wiley & Sons, Inc.
