9523657 Thomas This Americas Program award will support a research collaboration between Dr. J. Kerry Thomas, University of Notre Dame and Dr. Andres Olea, University of Chile, on a kinetic and thermodynamic study of anionic polyelectrolytes. The polymer systems to be studied are poly and copolymers of maleic anhydride and styrene. The P.I.'s intend to evaluate the effect of hydrophobicity and charge density on the microdomains generated in aqueous solutions of these polymers. The goals of the study are to identify the structural parameters which determine the formation and size of the hydrophobic aggregates; to evaluate the solubilization capacity of organic molecules by these aggregates; and to investigate by stopped flow studies the dynamic nature of both processes. This collaboration will benefit from the complementary expertise of the two researchers as well as from the facilities in both institutions. The University of Notre Dame has a variety of laser systems to excite photosystems with short pulses of light, and the University of Chile has a laboratory of polymer synthesis where both the synthesis and identification of the copolymers will be made. ***

9523657托马斯该计划奖将支持Notre Dame大学J. Kerry Thomas博士与智利大学的Andres Olea博士之间的研究合作，对阴离子聚电解质的动力学和热力学研究。 要研究的聚合物系统是甲基甲基苯乙烯和苯乙烯的聚合物和共聚物。 P.I.旨在评估疏水性和电荷密度对这些聚合物水溶液中产生的微域的影响。 研究的目标是确定确定疏水骨料的形成和大小的结构参数；评估这些骨料的有机分子的溶解能力；并通过停止流量研究两个过程的动态性质。 这项合作将受益于两位研究人员的补充专业知识以及两个机构的设施。 巴黎圣母院具有多种激光系统，可以激发光线短的光化系统，而智利大学则具有聚合物合成的实验室，在该实验室中既可以制作共聚物的合成和识别。 ***
