| Abstract: | The rheological properties of acrylonitrile copolymer in NaSCN\|aqueous were measured at various concentration. The relationships between shear rate, temperature or concentration and viscosity were established. The viscosity was characterized as a function of shear rate, temperature and concentration. The equation was used to viscosity calculation, giving the calculating uncertainty below ±2% as compared with the experimental result. |
