U.S.-Mexico: In-Situ Studies and Analyses of Crystallization and Fusion of Polyesters and their Copolymers

9404668 Phillips美国项目奖将资助一个高分子材料领域的研究项目的差旅费和相关费用。合作者是田纳西大学的Paul Phillips教授、墨西哥圣路易斯波托西大学的Francisco Medellin-Rodriguez教授和橡树岭国家实验室的J.S. Lin博士。将对一系列芳香族聚酯的二次结晶进行原位研究，目的是了解控制这一系列重要商用聚合物结晶和其他性质的分子特征。早期的研究尚未对二次结晶过程的分子机制给出明确的定义。本提案将基于以往研究的实验观察，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。这项研究的其他部分将在田纳西大学和圣路易斯波托西大学进行。* * *

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. ***
