Using different methods to study the properties of polycaproamide obtained by low-temperature hydrolytic polymerization of caprolactam and by commercial production (GrodnoKhimvolokno OAO), we have shown that the experimental samples have higher degree of oxidation and content of caprolactam and low molecular weight compounds. Since we previously established a correlation between these indices of the polymer and the strength characteristics of the filament made from it, despite the greater drawability of polycaproamide filaments obtained by low-temperature hydrolytic polymerization of caprolactam, the strength indices of the filaments formed from polycaproamide proved to be lower over the entire range of draw ratios.
