U.S.-Slovak Research on Modification and Characterization of Polymeric Media

INT 9604691 Weiss这项由乔治城大学的Richard Weiss博士和斯洛伐克科学院聚合物研究所的Pavol Hrdlovic博士共同开展的美国-斯洛伐克研究项目，将以研究聚合物体系内的光诱导动态过程的方法为特色。具体地说，研究人员打算：1)合成具有共价连接的发光报告基团的交联互穿网络(IPN)聚合物；2)形成含有能够增强或抑制直接和分子氧介导的光降解的基团的共聚物；以及3)测量小客体分子在这些聚合物中的扩散速率。这一合作努力建立在Weiss博士在光化学方面的专业知识和斯洛伐克研究所的聚合物合成能力的基础上，预计将产生关于聚合物光降解的新信息，并可能在工业材料中应用。这一联合项目通过使美国和东欧的顶尖专家能够将互补的人才结合在一起，并在具有强烈共同兴趣和能力的领域汇集资源，从而实现了促进科学知识的计划目标。?？

INT 9604691 Weiss This U.S.-Slovak research project between Dr. Richard Weiss of Georgetown University and Dr. Pavol Hrdlovic of the Slovak Academy of Sciences' Polymer Institute will feature development of methodologies for studying light-induced dynamic processes within polymeric systems. Specifically, the researchers intend to: 1) synthesis cross-linked interpenetrating network (IPN) polymers with luminescing reporter groups covalently attached at selected sites; 2) form copolymers containing groups capable of enhancing or inhibiting direct and molecular oxygen-mediated photodegradation; and 3) measure diffusion rates of small guest molecules within these polymers. This cooperative effort builds upon the expertise of Dr. Weiss in photochemistry and the Slovak institute's capacity for polymer synthesis and is expected to yield new information on polymer photodegradation with potential application in industrial materials. This joint project fulfills the program objective of advancing scientific knowledge by enabling leading experts in the United States and Eastern Europe to combine complementary talents and pool resources in areas of strong mutual interest and competence. ??
