Phase Equilibrium (VLE) Measurements in Ternary Mixture of SC CO2 + (0.564 Toluene/0.436 Chloroform) Underlying the SEDS Dispersion Process of Immiscible Polymer Blending

The paper presents the results of an experimental study of the solubility of an ethylene-vinyl acetate copolymer (EVA-113) and nitrile-butadiene rubber (NBR-18) in organic solvents (toluene, chloroform, and dichloromethane) in the temperature range from 308 to 373 K at atmospheric pressure. The codispersion of EVA-113 and NBR-18 polymers has been performed in the pressure range from 8.0 to 25 MPa at temperatures between 313 and 333 K using the solution enhanced dispersion by supercritical fluids (SEDS) method. The crystallization kinetics and phase transformations in the polymer blends, obtained by blending in a melt and using the supercritical SEDS methods (prepared by supercritical CO 2 ), were studied and compared. The effects of the EVA-113/NBR-18 ratio and operating conditions (T and P) on the thermal (heat of fusion) and mechanical (tensile strength and relative elongation) characteristics of obtained polymer blends were studied. It has been illustrated that the use of the SEDS technique with the conventional ratio of components of the EVA-113/NBR-18 blend makes it possible to obtain thermoplastic elastomer whose properties are superior to materials obtained by blending in a melt.
