Kinetics of Phase Separation in Partially Miscible Polymer Blends

部分相容聚合物混合物的相分离动力学：该奖项是根据1987/1988年美国-工业化国家科学家和工程师交流计划竞赛提出的。该计划旨在使美国科学家和工程师能够在西欧工业化国家以及日本、澳大利亚和新西兰的研究机构进行长期研究。交流奖为开展联合研究和利用外国独特或互补的设施、专门知识和实验条件提供了机会。奖项的评选依据是与其所在科学领域有关的科学标准、申请者在专业发展方面的潜在潜力以及与进一步促进科学和工程领域的国际合作有关的标准。该计划特别针对正在开始他们的研究生涯的科学家和工程师。本研究利用小角中子散射法研究了部分相容聚合物共混物中两相形态的初始关联长度和随后的发展和生长。这一过程将作为聚合物的相对分子质量和它们之间的相互作用的函数进行研究。这一结果将被用于评估当前的相分离理论。该项目由康涅狄格大学化学工程系和聚合物科学项目的Robert A.Weiss教授和英国伦敦SW7 2 by的化学工程和化学技术系R.W.H.萨金特教授领导。这项奖励建议提供资金，酌情支付国际旅行、当地出国旅行、津贴、家属津贴(如果适用)、语言培训(如果需要)，以及为美国本土机构提供250美元的固定行政津贴。

Kinetics of Phase Separation in Partially Miscible Polymer Blends: This award recommendation is made under the U.S.-Industrialized Countries Program for the Exchange of Scientists and Engineers, 1987/1988 Competition. The program is designed to enable U.S. scientists and engineers to conduct long-term research at research institutions in the industrialized countries of Western Europe as well as Japan, Australia and New Zealand. Exchange awards provide opportunities for the conduct of joint research and the utilization of unique or complementary facilities, expertise and experimental conditions in foreign countries. Awards are selected on the basis of scientific criteria relevant to his/her field of science, the prospective potential of the applicants for professional growth, as well as criteria relevant to the furthering of international cooperation in science and engineering. The program is particularly directed to scientists and engineers who are embarking on their research careers. This research project involves a study of the initial correlation lengths and subsequent development and growth of two phase morphology within the spinodals of partially miscible polymer blends using small angle neutron scattering. The process will be investigated as a function of the molecular weight of the polymers and the interactions between them. The result will be used to evaluate current theories of phase separation. The project is under the Direction of Professor Robert A. Weiss, Chemical Engineering Department and Polymer Science Program, University of Connecticut, Storrs, CT 06268, U.S.A., and Professor R. W. H. Sargent, Department of Chemical Engineering and Chemical Technology, London SW7 2 BY, England. This award recommendation provides funds to cover, as appropriate, international travel, local travel abroad, stipend, dependents allowance, if applicable, language training, if required, and a flat administrative allowance of $250 for the U.S. home institution.
