## Abstract Anionic polymerization of ϵ‐caprolactam was initiated with the potassium salt of ϵ‐caprolactam and accelerated with phenyl isocyanate, toluylene diisocyanate, 4,4′‐diphenylmethane diisocyanate, some derivatives of these isocyanates (urethanes, ureas, and allophanates), or combinations o
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
