✦ Synopsis

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 of the corresponding derivatives of open-chain alkylamides in tetrahydrofuran. The gradual rise in conductivity and u.v. absorption around 300 nm observed with these systems can be attributed to the formation of 3-oxoimide and 3-oxoamide structures by the condensation of imides.

When heating anionic polymerizates of 6-caprolactam, the polymerization degree of the product decreases. The instantaneous rate of the process depends on the concentration of catalytic components, temperature, and heating time. Initially, the process occurs as a consequence of splitting amide-bonds
