摘要：

A reversed-flow gas chromatographic method for studying the interactions between vinyl chloride monomer (VCM) and poly(vinyl chloride) (PVC) is described. The method permits the calculation of the VCM diffusion coefficient in the gas phase and the determination of the partition coefficient of VCM between PVC and the carrier gas (nitrogen). From the variation of the partition coefficients with temperature, differential thermodynamic parameters (enthalpy and entropy) of adsorption of VCM on PVC were calculated. These are discussed in comparison with the same parameters as determined by inverse gas chromatography.
