Obtaining a Composite Material from Thermodynamically Incompatible Polycarbonate and Polyethylene Terephthalate Polymers in the Process of Dispersion Using the SEDS Method

The paper presents the results of the experimental study of the phase equilibrium of the “CO 2 – N-methylpyrrolidone / chloroform” system (the ratio of organic solvents is 50 to 50% wt.) on isotherms 313.15 and 333.15 K in a pressure range of 0.98 – 11.91 MPa. The results of joint dispersion of polymer mixtures of polycarbonate and polyethylene terephthalate, carried out in a pressure range of 9–20 MPa at temperatures of 313–353 K using the SEDS method, are presented. The kinetics of crystallization and phase transformation in polymer mixtures obtained by mixing in a melt and using the SEDS method is studied.
