U.S.-Chile Cooperative Research Program: Kinetic and Thermodynamic Study of Anionic Polyelectrolytes

这个美洲项目奖将支持圣母大学的J. Kerry Thomas博士和智利大学的Andres Olea博士在阴离子聚电解质的动力学和热力学研究方面的合作研究。所研究的聚合物体系是马来酸酐和苯乙烯的聚和共聚物。侦探我们打算评估疏水性和电荷密度对这些聚合物水溶液中产生的微畴的影响。本研究的目的是确定决定疏水聚集体形成和大小的结构参数；评价这些聚集体对有机分子的增溶能力；并通过停止流动来研究这两个过程的动态性质。这一合作将受益于两位研究人员的互补专业知识以及两所机构的设施。圣母大学（University of Notre Dame）有多种激光系统，可以用短脉冲光激发光系统，智利大学（University of Chile）有一个聚合物合成实验室，可以进行共聚物的合成和鉴定。* * *

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. ***
