Shear and Pressure Effects on the Crystallization Kinetics of Semi Crystalline Polymers

在少数群体研究启动基金(MRI)的资助下，结晶聚合物的结晶速率将被研究其对流动诱导效应的敏感性。人们最感兴趣的是剪切效应。这项研究将探索几种聚合物的剪切应力、剪切速率、粘度和结晶速率随温度的变化关系。这种方法是实验性的，也是通过建模的方式。将对注射成型过程进行建模，并将结果与实验结果进行比较。结晶聚合物和注塑成型工艺是聚合物制造行业的重要组成部分。这项研究将增加以更准确和更有信心的方式控制产品和过程的能力。

Funded with a Minority Research Initiation Grant (MRI), crystallization rates for crystalline polymers will be investigated for their sensitivity to flow-induced effects. The primary interest is in the effect of shear. The study will explore the relationship between shear stress, shear rate, viscosity, and crystallization rate as a function of temperature for several polymers. The approach is experimental and also by way of modeling. The injection molding process will be modeled and the results compared to experimental findings. Crystalline polymers, and the injection molding process, are important elements in the polymer manufacturing industry. This research will add to the capability to control product and process with greater accuracy and confidence.
