All the copolymers have a cylindrical or spherical microdomain structure in the melt with the highly crystalline PCL block inside. In PCL-b-PB copolymers with M<SUB>n</SUB>≤19000, the SAXS result showed the morphological transition (microdomain structure→lamellar morphology) at each T<SUB>c</SUB> by the crystallization of PCL blocks. The repeating distance of the lamellar morphology increased significantly with increasing T<SUB>c</SUB>, as usually observed in the crystallization of homopolymers. The PCL crystallinity χ<SUB>c</SUB>(i.e., the weight fraction of crystallized PCL blocks against total PCL blocks in the system) was 0.58-0.79, comparable to that of PCL homopolymer. In PCL-b-PB copolymers with M<SUB>n</SUB>≥44000, on the other hand, the morphology did not change by the crystallization at any T<SUB>c</SUB>, and χ<SUB>c</SUB> was extremely reduced (x<SUB>c</SUB><0.15). The morphology formed in PCL-b-PB with M<SUB>n</SUB>=30000 was a combination of above two cases; the repeating distance was independent of T<SUB>c</SUB> and equal to that of the microdomain structure but the morphological transition was confirmed by SAXS and TEM. The relationship between the stabilities of the microdomain structure (or M<SUB>n</SUB>) and lamellar morphology (or T<SUB>c</SUB>) is qualitatively
