【 摘 要 】

In order to research the anti-Ageing property of temperature-resistant polymer solution at high temperature, the temperature-resistant polymer solution viscoelastic modulus are measured by type RS6000 rheometer with the temperature of 50 C, 95 C and the concentration of 1000mg/L, 1500mg/L, 2000mg/L. Then the viscoelastic modulus are measured after ageing 0∼90 days at 50 C and 95 C. The elastic modulus, viscous modulus, composite viscosity and first normal stress difference of temperature-resistant polymer solution improve with the rise of concentration, and decline with rise of temperature. After ageing 90 days at 50 C, viscoelastic modulus retention rate ranges from 85%∼93%. After ageing 90 days at 95 C, viscoelastic modulus retention rate ranges from 62%∼85%. The result shows that the temperature-resistant polymer is of good anti-Ageing property and temperature-resistant property.
