| Abstract: | Objective To study the rheology behavior of methacrylic acid copolymer Ⅱ and establish a method to measure its dynamic viscosity.Methods Dynamic viscosity was determined by malvern kinexus ultra concentric cylinder rheometer at a shear rate of 10 s-1 and 20 ℃.Results Methacrylic acid copolymer Ⅱ was newtonian fluid,whose dynamic viscosity was 5.06 mPa·s(RSD=0.25%,n=30).Conclusion The method is convenient,accurate and of good repeatability to determine dynamic viscosity of methacrylic acid copolymer Ⅱ. |
| Keywords: | Methacrylic acid copolymer Ⅱ Dynamic viscosity Concentric cylinder rheometer |
