The concept of viscosity is one of the central themes in rheology. There are many factors, including temperature T, pressure P, shear velocity , mass of polymer M and branching, which have great impacts on the shear viscosity of polymer solution. Based on the analysis and principle of each factor’s influence on the viscosity of polymer solution, a unified expression for the viscosity of polymer solution is put forward in this work. This new formula has two adjustable parameters (A and B), as well as three polymer constants ( M , n, C M ), where M is mass of polymer, n stands for the non-Newtonian index and C M is threshold mass for chain entanglememt of polymer.
