The paper studies the surface morphology of the initial polymers and the mixture using a scanning electron microscope SEM - EVO MA 10 (Zeiss, Germany). The X-ray phase analysis was carried out on a Panalytical Empyrean diffractometer. It has been proven that polymer mixtures based on domestic suspension polyvinyl chloride and ethylene-vinyl acetate copolymer, obtained by the method of "thermomechanical" mixing, are two-phase systems consisting of a phase of polyvinyl chloride and an ethylene- vinyl acetate copolymer. It was concluded that suspension polyvinyl chloride is fundamental in this system, which determines the main deformation-strength properties of the mixture. In the process of mixing a certain ratio of copolymer and thermoplastic, two-phase systems are formed, that is, mechanical mixtures of technologically compatible polymers with very close values of solubility parameters are formed. It has been determined that polymer mixtures based on domestic suspension polyvinyl chloride and an ethylene-vinyl acetate copolymer, obtained by the method of "thermomechanical" mixing, are two-phase systems consisting of a phase of polyvinyl chloride and an ethylene-vinyl acetate copolymer.
