摘要
考察了聚甲丙烯酸铵酯Ⅰ的流体特性并建立了其动力黏度的测定方法。采用马尔文Kinexus Ultra同轴圆筒式流变仪,测定温度20℃,剪切速率10 s-1。结果表明聚甲丙烯酸铵酯Ⅰ为牛顿流体,动力黏度为6.78 mPa.s,RSD为0.19%。
The rheology behavior of methacrylic acid copolymer I was investigated and a method was established for the determination of its dynamic viscosity. A M a 1 v e r n Kinexus Ultra concentric cylinder rheometer was used at 20 ℃ with the shear-rate of 10 s 1. The results showed that methacrylic acid copolymer I was a Newtonian fluid, whose dynamic viscosity was 6.78 mPa-s with RSD of 0.19% .
