C5 /C9 copolymer resin PR1-140 is a kind of thermoplastic resin produced by pre-treatment, polymerization, distillation and other processes from the C5 and C9 fractions by-produced by petroleum cracking. It is not a high polymer, but a molecular weight between 300- 3000 oligomers. It has the advantages of C5 petroleum resin and C9 petroleum resin. It has the characteristics of low acid value, good miscibility, water resistance, ethanol resistance and chemical resistance. It is chemically stable to acid and alkali, and has the characteristics of good viscosity adjustment and thermal stability. Since the structure does not contain polar groups, it has good water resistance, acid and alkali resistance, weather resistance and light aging resistance. It has good solubility in organic solvents, especially in petroleum solvents, similar to other resins. The compatibility is very good, and it also has brittleness, viscosity increasing, cohesiveness and plasticity. It is generally not used alone, but as an accelerator, regulator, modifier and other resins.
