摘要
综述了高聚物共混物熔体在流动过程中的弹性特征及规律，对不同共混物的弹性行为进行了归纳分类。发现相容性共混物体系的弹性随组成的变化是单调增减的，不相容共混物体系的弹性组成变化有几种情况：共混物的弹性参数介于两纯组分之间、共混物弹性出现最大或（和）最小值。
The elastic feature and law through the flow process of polymer blend melt were reviewed with 27 refrences. The elastic behavior of various blends were generialized and classified. It was conclused that the elasticity of miscible polymer blends changed with the composition linearly. While the elasticity of immiscible polymer blends changed with the composition very complicatedly. Which could be classified into three cases: the elastic parameters of polymer blends were between those of the pure polymers, there was a maximum or/and a minimum in the polymer blends′ elasticity, and the change trend of elasticity was the same as that of the viscosity.
