它示出了如何的动力学理论的聚合物熔体，由柯蒂斯和鸟，可以扩展到多分散的混合物。一个完整的本构方程，得到包含在混合物中的每一个组成部分的重量分数。给出了零剪切速率粘度函数（粘度和法向应力系数）和稳态剪切顺应性的显式表达式。与实验数据以及多分散聚合物熔体的Doi-Edwards理论进行了比较。
It is shown how the kinetic theory of polymer melts, as formulated by Curtiss and Bird, can be extended to polydisperse mixtures. A complete constitutive equation is obtained containing the weight fractions of each component in the mixture. Explicit expressions are given for the zero-shear-rate viscometric functions (viscosity and normal-stress coefficients) and the steady-state shear compliance. Comparisons are made with experimental data and with the Doi-Edwards theory for polydisperse polymer melts.
