Abstract
The paper addresses the study of the thermodynamic compatibility of carbon-chain polymer compositions of offset rubber blankets with low-molecular-weight liquids, paint solvents and care agents for rubber damping machine parts used in transport, mechanical engineering and printing industries. The Flory-Huggins parameters χ were determined by inverted gas chromatography and calculation performed using the mathematical model of sorption, and the correlation between χ obtained by these two independent methods was found. The excess thermodynamic characteristics of the studied systems G E, H E and S E were calculated to predict the compatibility of components in these systems. The relationship was found between χ that characterizes the thermodynamic quality of the solvent and the equilibrium swelling index of polymer networks.
