## Abstract Heteroarm star copolymers bearing poly(2βvinylpyridine) and polystyrene arms (A~__n__~B~__n__~ type) were synthesized by a threeβstep anionic polymerization method. Polystyrene arms are synthesized first, and they are used to initiate the polymerization of a small amount of divinylbenze
A macro-azo initiator (MAI), prepared by polycondensation of azobiscyanopentanoyl chloride (ACPC) and polyethyleneglycol having average molecular weight of 1000 (PEGlOOO), was found to show enough surface activity t o be usable as a n initiator/surfactant (inisurf). Emulsion polymerization of styre
