使用毛细管流变仪对热塑性淀粉 (TPS) 进行流变表征，包括研究其流动特性，具体取决于混炼参数、掺入添加剂的类型和含量以及熔融温度。基于大量的实验研究，甘油解构TPS类型的粘度函数可以通过定义新的组合位移因子来分析描述，该因子考虑了熔体温度和添加剂用量的影响。由于特定的 TPS 配方而产生壁滑移效应；通过应用修改后的门尼程序进行量化。
The rheological characterization of thermoplastic starches (TPS) by using a capillary rheometer includes the research of their flow properties depending on compounding parameters, on types and contents of incorporated additives, as well as on melt temperatures. Based on extensive experimental studies, the viscosity functions of glycerol de-structurized TPS types can be described analytically by the definition of a new combined shift factor, which considers the influence of both melt temperature and additive amount. Wall-slip effects due to specific TPS formulation; were quantified by the application of a modified Mooney procedure.
