In this study, petroleum polymer resins (TAR) were obtained from the secondary products of the pyrolysis process using a partially oxidative pyrolysis method. The chemical composition and structural properties of the resins were thoroughly investigated. The pyrolysis was conducted at temperatures ranging from 120 to 140 °C for durations of 2, 4, and 6 hours under staged air injection conditions. The resulting gases, including methane, ethane, propane, butane, CO, and CO₂, were analyzed. The liquid fractions were separated by vacuum distillation into light and heavy fractions. The heavy fraction was dissolved using solvents, filtered, and the pure resin was recovered through solvent evaporation. Mass spectrometry analysis identified anthracene (C₁₄H₁₀) as the primary component of the product. The physicochemical properties of the resin included a density of approximately 1.2 g/cm³, a softening point between 120–140°C, and high viscosity. This method offers a viable approach for obtaining high valueadded aromatic resins from waste materials.
