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. ??

INT 9604691韦斯 这个美国-乔治敦大学的Richard韦斯博士和斯洛伐克科学院聚合物研究所的Pavol Hrdlovic博士之间的斯洛伐克研究项目将以开发研究聚合物系统内光诱导动态过程的方法为特色。 具体来说，研究人员打算：1）合成交联互穿网络（IPN）聚合物，其中发光报告基团共价连接在选定的位点; 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; 3）测量这些聚合物中小客体分子的扩散速率。 这一合作努力建立在韦斯博士在光化学方面的专业知识和斯洛伐克研究所在聚合物合成方面的能力的基础上，预计将产生关于聚合物光降解的新信息，并有可能应用于工业材料。 这个联合项目实现了促进科学知识的方案目标，使美国和东欧的主要专家能够在共同感兴趣和有能力的领域联合收割机互补人才和集中资源。 ??
