Facile synthesis of well-defined ABC miktoarm star terpolymers bearing poly(ε-caprolactone), polystyrene and stereoregular helical poly(phenyl isocyanide) blocks

Abstract

A novel strategy for the facile synthesis of ABC miktoarm polymers bearing poly(ε-caprolactone) (PCL), polystyrene (PS), and stereoregular helical poly(phenyl isocyanide) (PPI) blocks has been developed. A Pd(II) mid-functionalized PCL-b-PS block copolymer was first prepared in a controlled manner, which initiated the living polymerization of phenyl isocyanide, affording the well-defined ABC miktoarm star terpolymer.
