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
## 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
~ct--The anionic graft polymerizations of methacrylonitrile on starch in dimethylsulphoxide, initiated by the lithium and sodium alkoxide derivatives, were studied; the results were compared with those previously obtained with the corresponding potassium alkoxide. With lithium the results were not h
