A novel empirical equation for intrinsic viscosity determination of polymer solution by one point method is reported. The results of comparison investigation between this equation and Cheng Rongshi’s equation by using the data reported in the literatures indicate that new equation possesses higher accuracy and broader applicability than Cheng’s equation, and it is simple and easy for operation.

Key words: intrinsic viscosity, one point method, polymer, polymer solution, viscosity determination
