Human volunteers were exposed to artificially generated caprolactam vapors to establish irritant response and discomfort threshold. At high relative humidities, response was absent at all concentrations up to 14 ppm. At low relative humidities, distress was dose responsive in the range 10-100 ppm. There was no response below 7 ppm.

Polymerization of caprolactam. Part IV. Stannic chloride ‐ caprolactam complex
Die Makromolekulare Chemie, 1967AbstractSnCl4 forms a 1:2 molar complex with caprolactam, and the role of this complex in initiating the polymerization of caprolactam has been studied. At the temperature of polymerization, the complex decomposes with the evolution of two moles of HCl per mole of complex.

AbstractThe anionic polymerization of ∈‐caprolactam initiated with magnesium initiators was studied in the interval 180–250°C. ∈‐Caprolactam magnesium bromide was much more active than magnesium di(∈‐caprolactamate) and the activity of both depended on the way of their preparation.

Journal of Polymer Science, 1959
AbstractThe equilibrium resulting from the water initiated polymerization of caprolactam has been investigated for initial water concentrations (w) in the range, 0.01 ≤ w ≤ 1 (moles H2O/mole caprolactam) at temperatures 220, 235, 250, and 265°C. Based upon the postulate that, at a given temperature, the degree of polymerization is directly proportional

Transformation of low‐molecular linear caprolactam oligomers by caprolactam‐degrading bacteria
Journal of Chemical Technology & Biotechnology, 2012AbstractBACKGROUND: Wastes generated in production of caprolactam (2‐oxohexamethylenimine, ε‐caprolactam) and caprolactam‐based polymers contain the unreacted monomer and its low‐molecular linear and cyclic oligomers. Application of microorganisms for biological treatment of caprolactam‐ and oligomer‐containing wastes can become an alternative to ...
