Abstract: Microscopic, conductometric, and viscometric methods have shown that when combining primary powdered waste from the production of polyvinyl chloride (screenings, filter cake, crust, dust) and polystyrene (screenings), there are several characteristic temperatures: the swelling temperature (50…70 °C), corresponding to the transition of the polymer from glassy to highly elastic state; the temperature of dispersion of polymer particles on aggregate-globular formations as a result of the swelling pressure of the y-fraction of coal binders sorbed by polymer particles; dissolution temperature (105…125 °C). The optimal preparation time for tar-oil polymer binders (TOPB) at dissolution temperatures is 50–70 minutes. Under these temperature-time conditions for the production of TOPB, the maximum adhesion of the tar-polymer binder to the surface of mineral materials and the elasticity of the modified organic binder are achieved.

Keywords: tar-oil polymer binders, primary waste from the production of polyvinyl chloride and polystyrene, temperature-time regimes for the production of tar-oil polymer binders.
