The results of an experimental study of the phase equilibrium (VLE) properties of CO2 in organic mixture of (0.564 toluene/0.436 chloroform) at three selected isotherms of 313.15 K, 333.15 K, and 353.15 K in the pressure range from (0.95 to 12.27) MPa, involved in the supercritical SEDS dispersion process of immiscible polymer blending, are reported in the present work. The compatibility of immiscible linear high-pressure polyethylene (HPPE)/polycarbonate (PC) polymer blends with organic toluene + chloroform solvent in the presence of supercritical carbon dioxide (SC CO2) was studied. The PC and LHPPE polymers blending have been carried out in the pressure range from (8 to 25) MPa at temperatures between (313.15 and 353.15) K using the supercritical SEDS method. The kinetics of crystallization and phase transformation in polymer blends obtained by the melt blending (mixed in the molten state) and the supercritical SEDS methods have been studied using DSC technique. The thermodynamic characteristics such as (temperature, t fus , and enthalpy of fusion, Δ fus H ) of the produced LHPPE/PC polymer blends are presented. The influence of the supercritical SEDS dispersion process parameters on the heat of fusion of the obtained LHPPE/PC polymer blends has been studied. The compatibility of LHPPE/PC blends was confirmed by studying the DSC melting-crystallization curve properties and investigating the morphology. The morphology of the LHPPE/PC polymer blends was examined using a scanning electron microscope (SEM) and the particle sizes depending on the operating temperature and pressure were studied.
