The Arabian asphaltene reinforced polystyrene composites include a matrix of polystyrene and an asphaltene filler isolated from Arab heavy crude oil residue that is distributed within the polystyrene matrix to form the Arabian asphaltene reinforced polystyrene composite. Asphaltenes are obtained from the Arab crude oil by precipitation in n-heptane. Styrene monomer and the asphaltenes filler are polymerized by using heat to initiate in situ polymerization. Testing shows that the asphaltene reinforced polystyrene composites have improved viscoelastic properties (e.g., flexural strength) and thermal stability.
