Experimental study of sorption and diffusion in semi-crystalline polymers
Original language description
The main goal of this work is to analyse the dependence of the ethylene solubility on the polymer properties and temperature. In the case of PE, the dependency on temperature and PE density (crystallinity) was investigated. Subsequently, the ethylene solubility in the amorphous phase of PE was evaluated and the observed solubility trends discussed. For the evaluation, the temperature dependent crystallinity and swelling were both considered, which was not yet presented in the literature. In the case ofhiPP, the dependency of the ethylene solubility on temperature, the content of EPR and the composition of EPR were investigated. Finally, ethylene solubilities in the amorphous phase of PE were fitted by the perturbed-chain statistical associating fluidtheory (PC-SAFT) equation of state. The calculated isotherms were in a good agreement with the experimental data at all temperatures and for all measured PE samples. PC-SAFT enables to extrapolate experimental data, predict the phase equi
