Abstract

Two petroleum-derived aromatic hydrocarbon resins (HRs) were blended (1:1) with expanded polystyrene (EPS) waste and small amounts (up to 10 mass%) of poly(vinyl chloride) (PVC) to increase both the lustrous carbon (LC) yield and softening point of the blends without any deterioration of their rheological characteristics. The blends were prepared and tested for LC content, softening points, shear stress and apparent viscosity to check their applicability as LC precursors under industrial conditions.

The properties of polystyrene compositions with bitumen fractions depend primarily on composition and viscosity of oil fraction. Additional modification by poly(vinyl chloride) improves the blends’ properties, like bright coal content, softening point and viscosity, and opens new possibilities of plastics’ wastes utilization.
