Abstract
The methods of cloud points, X-ray diffraction, DTA, and polarization and e lectron microscopy were used to study the relaxation character of the phase separation in the polypropylene-chlorobenzene and polypropylene-poly(vinyl alcohol) systems. The concentration dependences of the parameter of intera ction between the components were calculated. An increase in the cooling ra te of solutions and blends results in a considerable shift of the boundary curves and in a change of their shape due to changeover from crystalline- t o amorphous-type phase separation.
