Abstract Size Exclusion Chromatography(SEC) was used to investigate the micelle forming behavior of Poly(styreneisoprene) diblock copolymers, with same composition and various molecular weight in different selective solvents at different temperatures. The aggregation number and aggregation energy of micelle can be determined. The effects of selective solvent, temperature and molecular weight of PS‐PI on micelle forming behavior have been discussed.
