The rate constants of polymerization and cyclization and the equilibrium constants of polymerization are calculated from kinetic data of the anionic oligomerization of methyl methacrylate initiated by methyl a-lithioisobutyrate in THF at 25 "C, and of the "disproportionation" of living oligomers.

## Abstract The successful activation observed when using Bu^__t__^P~4~ phosphazene base and thiophenol or bisthiols for the anionic ring opening polymerization (ROP) of di‐__n__‐propyl cyclopropane‐1,1‐dicarboxylate is described. Well‐defined monofunctional or difunctional polymers with a very nar
