In this paper, differential scanning calorimetry (DSC) was used to study non-isothermal crystallization behaviors of tri-block copolymer poly(styrene)-b-poly(ethylene oxide)-b-poly(styrene) (SEOS). Homopolymer poly(ethylene oxide) (PEO) with almost the same molecular weight as PEO block was also studied comparatively under non-isothermal conditions. From final degree of crystalline X (c) and given degree of polymerization N, relative degree of crystalline X (t) at different kinetics stage was changed to be monomer units numbers involved in crystallization process. Based on well-recognized model of PEO crystalline structure, X (t) at specific stage can be used to calculate the scales of PEO crystalline. Comparing the crystallization behaviors of SEOS with those of PEO, it is indicated that confinement from solidified PS block restricts the mobility of PEO chain to form a pre-ordered structure in initial stage and decreases its lamellae thickness of nucleus that dominates the whole crystallization process.
