9404668 Phillips This Americas Program award will fund travel and related expenses on a research project in the area of polymeric materials. The collaborators are Professors Paul Phillips, University of Tennessee, Francisco Medellin-Rodriguez, University of San Luis Potosi, Mexico, and Dr. J.S. Lin, of Oak Ridge National Laboratories. In-situ studies of secondary crystallization in a series of aromatic polyesters will be carried out, with the goal of understanding the molecular features that control crystallization and other properties of this important series of commercial polymers. Earlier studies have not produced a well-defined molecular mechanism for the secondary crystallization process. This proposal will consider a new possible mechanism, based on experimental observations from previous studies. Much of the experimental work will be carried out at Oak Ridge National Laboratories, which is making its small-angle X-ray scattering research facilities available to Dr. Medellin. Other components of the research will be carried out at the University of Tennessee and at the University of San Luis Potosi. ***

9404668菲利普斯 该美洲计划奖将资助聚合材料领域研究项目的差旅费和相关费用。 合作者是田纳西大学的保罗菲利普斯教授、墨西哥圣刘易斯波托西大学的弗朗西斯科麦德林-罗德里格斯和J. S.林博士，来自橡树岭国家实验室。 将进行一系列芳香族聚酯中二次结晶的原位研究，目的是了解控制这一重要系列商业聚合物的结晶和其他性能的分子特征。 早期的研究还没有产生一个明确的分子机制的二次结晶过程。 该提案将根据以前研究的实验观察结果考虑一种新的可能机制。 大部分实验工作将在橡树岭国家实验室进行，该实验室正在向麦德林博士提供其小角度X射线散射研究设施。 研究的其他部分将在田纳西大学和圣刘易斯波托西大学进行。 ***
