摘　　要：以经典的Huggins方程和特性黏度为理论基础,通过测定聚合物共混物稀溶液黏度来确定共混物相容性。对相容性判据△b、△B、α、μ和k23进行了分析归纳,并用实例说明了此方法的可行性。A approach to the miscibility determination of polyblends by dilute-solution viscosity （DSV） was simple, swift and convenient. The method is derived from the classical Huggins equation, and rest on the validity of an additivity law pertaining to intrinsic viscosity. The polyblends miscibility was determined by the measurement of dilute-solution viscosity. The miscibility criterions such as△b、△B、α、μ and k23 were analyzed and classi- fied, and practical instances were used to show the feasibility of the DSV.
