## Abstract **Summary:** Tetraanilineβ__block__βpoly(Lβlactide) diblock oligomers are synthesized via ringβopening polymerization. The diblock oligomers cast from an Lβlactide selective solvent (chloroform) show spherical aggregates for the leucoemeraldine state, and ringβlike structures that are c
## Abstract ROP of PCL was realized in the presence of mPEG with $\overline M \_{\rm n}$β=β5β000, using Zn(La)~2~ as a catalyst. The resulting diblock copolymers with molar ratios of the CL/EO repeat units from 0.2β5.0 were characterized by DSC, WAXD, SEC, and ^1^H NMR. Melt crystallization was stu
