U.S.-Czech Materials Research on Kinetics of Microphase Separation in Copolymers

INT 9600679 Bansil 这个美国-波士顿大学的拉马·班西尔博士和高分子化学研究所的Cestmir Konak博士之间的捷克材料研究项目将研究几种共聚物体系中的微相分离现象，包括嵌段、接枝、无规和无规多嵌段共聚物。 为此，研究人员打算将时间分辨小角光散射（SALS）和时间分辨小角X射线散射（SAXS）技术联合收割机结合起来，对嵌段共聚物的微相分离动力学和结构进行系统的研究。他们的目标是确定相分离过程的哪些特征是通用的，哪些特征取决于特定的化学相互作用。 研究结果应提高我们的基本理解之间的关系的聚合物的结构和它们的特定的相互作用与溶剂。 结果可能在粘合剂、乳化剂和阻隔材料等领域具有技术应用。 该聚合物研究项目通过使美国和东欧的专家能够联合收割机互补人才并在具有强烈共同兴趣和能力的领域共享研究资源，实现了推进科学知识的计划目标。 ??

INT 9600679 Bansil This U.S.-Czech materials research project between Dr. Rama Bansil of Boston University and Dr. Cestmir Konak of the Institute of Macromolecular Chemistry will examine microphase separation phenomena in several copolymer systems, including block, graft, random, and random multiblock copolymers. To do so, the researchers intend to combine techniques of time-resolved small angle light scattering (SALS) with time-resolved small angle x-ray scattering (SAXS) to perform a systematic examination of microphase separation kinetics and structure in block copolymers. Their objective is to determine which features of the phase separation process are universal and which depend on specific chemical interactions. Findings should improve our basic understanding of the relationship between the structure of polymers and their specific interactions with solvents. Results may have technological applications in areas such as adhesives, emulsifiers, and barrier materials. This project in polymers research fulfills the program objective of advancing scientific knowledge by enabling experts in the United States and Eastern Europe to combine complementary talents and share research resources in areas of strong mutual interest and competence. ??
