## Abstract The influence of methyl substituent on the mechanism of the ringβopening polymerization of Ξ²βlactones initiated by alkali metal alkoxides is discussed. Attention has been paid to the effect of the substituent position in the monomer molecule on the ringβopening mechanism, the 3,3βdimeth

The anionic polymerization and oligomerization of 4-vinyl pyridine by methanolic alkali metal methoxides in DMSO was studied. The molecular weights increased with increasing monomer concentration and decreased with increasing methanol concentration. This fact was utilized in the preparation of oligo
The anionic oligomerization of acrylamide by methanolic alkali metal methoxides was studied in methanol and in aprotic solvents. Oligomer yield increased with increasing initiator concentration, the dielectric constant of the solvent, the electropositivity of the alkali metal and with decrease in me
