Specific Features of the Modification of Polyvinyl Chloride with Polystyrene Plastics

We determine the influence of the nature of polystyrene modifiers on the compatibility of polymers in plasticized polyvinyl-chloride materials. The revealed good compatibility of polyvinyl chloride with polystyrene suspensions, as compared with the impact-resistant polystyrene, is confirmed by the results of scanning electron microscopy. We establish the influence of the content of polystyrene modifier and fine polymer-silicate composites on the physicomechanical and thermal properties of modified polyvinyl- chloride plastics. It is shown that if we insert different amounts of polystyrene modifiers, then it is possible to regulate the physicomechanical properties of plastics and, especially, their elasticity. At the same time, we can increase the thermal stability of the material by adding finely divided metalcontaining polymer-silicate fillers.
