8. sec-BuLi, which initiates a living anionic polymerization of cyclic carbonates with 6-membered rings, is reported to be also effective for the polymerization of 7CC, though the polydispersity of the obtained polymer is rather broad: J.

14. 3 units were not incorporated into the produced polymer. Thus, the possibility of cationic chain growth of the polymerization is excluded
