摘要：

A new chromatographic method is reported for characterization of polyamides and polyether-block-amide copolymers by size exclusion chromatography. The GPC analysis of polyamides and copolymers is based upon the dual detection refractometer/on-line continuous viscometer at 130°C using columns packed with cross-linked polystyrene gels, benzyl alcohol as mobile phase and polytetrahydrofuran standards for calibration. The main results are absolute average molecular weights and distribution curve, intrinsic viscosity and viscosity law.
