The kinetics of the model reaction between ethylene glycol and N-acetyl-ϵ-caprolactam in the presence of different catalysts was investigated using differential isothermal calorimetry. Tetrabutyl orthotitanate was shown to be the most effective cata

Differences between the IR and Raman spectra of the dicaprolactamates of Mg, Ca, and Ba indicate differences in their structures. Barium dicaprolactamate has an ionic structure, while the dicaprolactamates of Mg and Ca are partially covalent and have

Based on analysis of the IR and Raman spectra of Na and K caprolactamates it has been established that these exist not in two forms (lactamic and lactimic), as previously proposed, but rather in one form, intermediate in structure between these two f

The exchange of acyl groups between N -acyllactams or N , N -diacylalkylamines and potassium salts of lactams or N -alkylamides was followed in THF at the initial molar ratio approx. 1:1 in systems either where propagation and other acylation reactio

The results of this study have shown that the poly (amido) esters formed during the copolymerization of ϵ-caprolactam with ϵ-caprolactone will be subject to exchange reactions between the macromolecules, and that these will be accompanied by ruptur

The two stage method of preparation of block copolyamides described below involves the synthesis of a macromolecular activator of anionic polymerization of caprolactam by reacting hexamethylenediamine with N,N′-isophthaloyl-bis-ϵ-caprolactam (firs

1. It was shown that it is theoretically possible to copolymerize ɛ-caprolactone with ɛ-caprolactam in the presence of triisobutylaluminum, which leads to the formation of poly(ester amides) with a high molecular weight. 2. In order to find the opt
