✦ Synopsis

This article refers to a study of the thermal behaviour of poly(ethylene oxide) and poly(vinyl chloride) blends in the solid state. The compatibility has been examined by differential scanning calorimetry. The influence of molecular masses of the polymers on their compatibility has been shown. The equilibrium melting temperatures decrease in the mixture, such behaviour being progressively greater with the PEO reduction. The melting temperature of blends increases linearly with the crystallization temperature for a wide range of undercooling. Values of the parameters ~(12 and B have been obtained.
