Objective: To study the Rheology behavior of Polyacrylic ResinⅢand establish a method to measure it's dynamic viscosity. Method: A Malvern Bohlin Gemini HRnano Concentric cylinder rheometer was used to develop the method at the Shear-Rate 10(1/s).Temperature when the test was carried out was 20 ℃. Results: Polyacrylic ResinⅢ was newtonian fluid,whose dynamic viscosity was 129.95 MPa·s(RSD=0.6%,n=30). Conclusion: The Method is convenient,accurate and reproductive for the control of the dynamic viscosity of the Polyacrylic ResinⅢ.
