The anionic heterogeneous polymerization of acrylonitrile in petroleum ether by nbutyllithium was studied under various experimental conditions. The dependence of the molecular weight on the total concentrations of the monomer and initiator was strongly affected by the momentary concentration of mon

## 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
