基于第1部分和第2部分的原始链模型，给出了缩合聚合物体系的流变本构方程。本构方程具有BKZ方程的形式，并给出了流变参数随分子量和浓度变化的记忆核的显式形式。有趣的是，它预测了非线性粘弹性状态下的应力叠加规律。总体特征与实验结果相当吻合。
The rheological constitutive equation of a condensed polymer system is presented based on the primitive chain model presented in Parts 1 and 2. The constitutive equation has the form of a BKZ equation and gives an explicit form for the memory kernel with the dependence of the rheological parameters on molecular weight and concentration. An interesting point is that it predicts a stress superposition law in the regime of non-linear viscoelasticity. The general features agree with experiments fairly well.
