Size-exclusion chromatography of low molecular weight polymers

Abstract To overcome the difficulty of the determination of the molecular-weight characteristics by size exclusion chromatography in the low-molecular-weight region (M < 104), the Sadron-Rempp relationship was used both for the construction of dependence of the universal calibration parameter on elution volume and for the tranformation of chromatographic data to molecular characteristics. Numerical values of constants of the above relation between intrinsic viscosity and molecular weight, which were calculated for some polymer-eluent systems on the basis of literature data, are given.
