摘要
本文研究了无现聚醚／水体系的粘温粘政特性，并对其流变性及粘弹性质进行了讨论。结果表明，其粘温曲线上存在粘度突跃，60％、70％处的粘度突跃是由于体系处于相分离状态而产生的。在低于50℃时，该体系呈牛顿型流体。在低频率作用下，体系呈现粘性流体。当频率大于10rad／s时，体系由粘性转为弹性体，此时流动阻力增大。
In this paper,the property of viscosity temperature as well as the viscosity-concentration of the random polyether/H,O system is studied togethel with its rheology and visco-elastic property. The results state that there is a viscosity jump in the figure of viscosity temperature which is caused by the phase separation at the concentration of 60% or 70%. This system shows the Newtonian fluid from 20℃ to 50 ℃. Under low frequency,this 'system shows as a viscous fluid. It will change to elastomer when the frequency is above 100 rad/s and thus causes the high fluid resistant.
