The molecular weight determination of polycaprolactam by the end-group titration was studied with conductometric, potentiometric and visual methods.Both amino and carboxyl end-groups could be titrated in the solvent at the same temperature.The sample was dissolved in henzyl alcohol at about 135°, to 60°and then diluted with suitable amount of methanol-water mixture(2:1 by volume).
