C5/C9 Copolymerized Hydrocarbon Resin is a thermoplastic hydrocarbon petroleum resin,refined by  C5, C9 fraction of petroleum by-product of decomposition with processing pre-treatment, polymerization and distillation. It is not a high polymer, but low polymer with the molecular weight range of 300-3000.C5/C9 has advantages both of C5 and C9 petroleum resin: low acid value, good miscibility, waterproof, ethanol resistance and chemical resistance and other characteristics of acid resistance, chemical stability in acid-bases,adjustment in viscosity, good thermal stability, weather resistance and light aging resistance because of non-polar groups in its structure. C5/C9 has good solubility in organic solvents especially in oil solvent, as well as good compatibility with other resins. It also has brittle, increasing viscosity, cohesiveness and plasticity. Generally, it is not used alone, but used as accelerant , regulator and modifier together with other resins.
