Asphaltic resins are synthesized from residual oil, FCC slurry and other aromatic hydrocarbon materials. With the catalyst, it is complicatedly connected by cross linking agent and become macromolecular substance with the basic structural unit of polycyclic aromatic hydrocarbons. This product enjoys good quality of high-temperature resistance, compatibility, agglutinating value and magnetic property, which can be used in waterproof roll, high grade road asphalt, heavy tar pitch and other polymers.
