橡胶流动区应力松弛的经验公式已被应用于商业和窄分布聚苯乙烯。所涉及的参数在数学上与剪切粘度8和稳态剪切柔量有关。文中还给出了各参数与样品平均分子量之间的关系。对完全单分散物种进行了外推，并讨论了它的意义。
An empirical equation for stress relaxation in the rubbery flow region has been applied to commercial and narrow-distribution polystyrenes. The parameters involved have been mathematically related to the shear viscosity, 8, and steady-state shear compliance,. Relationships between the parameters and the molecular weight averages of the samples are also presented. An extrapolation to a completely monodisperse species is performed and its implications are discussed.
