摘要：
The formation of block copolymer mixed micelles has been studied in solutions of polystyrene-block-polyisoprene and polystyrene-block-poly(ethylene-co-propylene) in decane, a selectively poor solvent for polystyrene blocks. The rate of mass exchange-between two types of micelles, studied by the sedimentation velocity method, depends strongly on the rates of micelle formation and dissociation processes, which can be controlled by temperature.
