## Abstract ROP of PCL was realized in the presence of mPEG with $\overline M \_{\rm n}$โ=โ5โ000, using Zn(La)~2~ as a catalyst. The resulting diblock copolymers with molar ratios of the CL/EO repeat units from 0.2โ5.0 were characterized by DSC, WAXD, SEC, and ^1^H NMR. Melt crystallization was stu
## Abstract The effect of crystallization temperature on the micellar morphology of PCLโ__b__โPEO block copolymers in water has been studied. It is found that the micellar morphology of PCL~__n__~PEO~44~ and PCL~__n__~PEO~113~ changes with crystallization temperature in different ways because of tw
