Abstract

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 oligomers. Evidence is given that initiation is an acid-base reaction. Methanol leads not only to transfer but participates in solvation of the methoxide and growing carbanions affecting the rate of reaction. The rate of reaction decreases with increasing methanol concentration.
