## Abstract A method to determine the concentration of ϵ‐aminocaproic acid (ACA) in poly‐ϵ‐caprolactam by high‐pressure liquid chromatography is established. The polymerizations for initial water concentrations of 0.42, 0.82, and 1.18 mol/kg and temperatures of 230, 240, 250, 260, 270, and 280°C we
## Abstract The concentrations of the cyclic oligomers (__C__~__i__~; __i__ = 3, 4, 5, and 6) in the polymeric products of ε‐caprolactam were determined by high‐performance liquid chromatography. The equilibrium data on the oligomers were obtained as a function of the polymerization temperature and
