The point of view was advanced that in spinning fibres from polymer melts, the molecular inhomogeneity of the melts is not due to the polydispersity of the polymer but to important differences in the average molecular mass of the individual granules.

Experimental confirmation of the thermodynamic identity of condensation reactions of amino and carboxyl groups in PCA melt and amorphous phase was obtained. It was shown that the Huggins constant of PCA uniformly increases with an increase in the tim

Using aminolysis of caprolactam by diethylenetriamine, it is shown that the rate constant of this reaction is almost independent of the basicity of the aliphatic amine, but it decreases significantly in going from a melt of a mixture of amine and cap

High-molecular-weight block copolymers of polycaproamide and polyethylene glycol were synthesized and are distinguished by the different size of the polyamide block and number of polyamide and polyethylene oxide blocks in the macromolecule. In the co

It was found that preliminary treatment of PCA granulate with a dilute solution of CH3COOH sharply increases the rate and degree of sorption of acid dyes by PCA granulate. A technological regime for dyeing PCA granulate with acid dyes was proposed an

The possibility of synthesis of fibre-forming block-copolymers of polycaproamide and polyethylene glycol by a reaction of chain lengthening of prepolyamides prepared by cationic polymerization of caprolactam in the presence of 100% H3PO4 has been dem

Final polyamidation of polycaproamide below the melting point of the polymer, carried out in an inert medium, is not accompanied by the appearance of nonlinear macromolecules, even when the process is carried out for a comparatively long time.

A kinetic study of the cationic polymerization of caprolactam (CL) catalyzed by anhydrous H3PO4 has been carried out in the 220–240°C range using a 1–4 mole% catalyst concentration. The reaction has been found to be of first order with respect t
