The non-activated polymerization of e-caprolactam initiated with the sodium salt of e-caprolactam (CLNa), which was prepared in situ with sodium methoxide, was studied in the temperature range 170 -230 8C and at CLNa concentrations from 0.20 to 1.0 mol-%, and at 190 8C in the presence of 2.0 -10.0 m

## 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
Interactions between potassium salts of lactams and N-acyllactam propagation centres in the initial stage of the anionic polymerization of lactams were studied by measuring changes in the electric conductivity and in the i.r. spectrum in the range of carbonyl vibration bands of these compounds and o
