Abstract

Formation of star-shaped nanomicelles of polyisobutylene-polystyrene (PIB-PS) diblock copolymers in hexane solution is reported. The length of the polystyrene segments were varied in the M(n) range of 4000-13000 g/mol at approximately constant polyisobutylene segments length. The size and the size distribution of the nanomicelles were investigated by dynamic light scattering. Based on static light scattering measurements the mass-average molecular mass of the micelles and the number of arms were also determined. The synthesized diblock-copolymers were demonstrated to be capable of stabilizing the growing particles which were formed in the living anionic dispersion polymerization of styrene in hexane.
