We describe the full rheology profile of vitrimers, from small deformation (linear) to large deformation (non-linear) viscoelastic behaviour, providing concise analytical expressions to assist the experimental data analysis, and also clarify the emerging insights and rheological concepts in the subject. We identify the elastic-plastic transition at a time scale comparable to the life-time of the exchangeable bonds in the vitrimer network, and propose a new method to deduce material parameters using the Master Curves. At large plastic creep, we describe the strain thinning when the material is subjected to a constant stress or force, and suggest another method to characterize the material parameters from the creep curves. We also investigate partial vitrimers including a permanent sub-network and an exchangeable sub-network where the bond exchange occurs. In creep, such materials can exhibit either strain thinning or strain thickening, depending on applied load, and present the phase diagram of this response.

我们描述了玻璃体的完整流变学特征，从小变形（线性）到大变形（非线性）粘弹性行为，提供简明的分析表达式以协助实验数据分析，并阐明该主题中新兴的见解和流变概念。我们在与 vitrimer 网络中可交换键的寿命相当的时间尺度上识别弹塑性转变，并提出了一种使用主曲线推断材料参数的新方法。在大塑性蠕变中，我们描述了材料受到恒定应力或力时的应变变薄，并提出了另一种从蠕变曲线表征材料参数的方法。我们还研究了部分玻璃体，包括永久子网络和发生键交换的可交换子网络。在蠕变中，这种材料可以表现出应变变薄或应变变厚，具体取决于施加的载荷，并呈现该响应的相图。
