项目摘要

9411483 Smid This U.S.-Bulgaria Joint Cooperative Research project on "Associative Star Polymers of Poly(ethylene oxide)" is a renewal of a grant between the research group of Dr. Johannes Smid of the SUNY College of Environmental Science & Forestry and that of Dr. Christo Tsventanov of the Institute of Polymers of the Bulgarian Academy of Sciences. The project deals with the synthesis, properties and utilization of materials related to poly(ethylene oxide), a polymer manufactured in both Bulgaria and the United States. Specifically, the work to be performed at the SUNY- Syracuse campus would involve associative star polymers with poly(ethylene oxide) arms end-capped with a hydrophobic moiety. Such star polymers, presently being investigated in our laboratory, cause phase separation when added to water, with formation of a polymer rich gel phase. This phase has a high capacity and affinity for hydrophobic organic solutes. The project aims to synthesize and characterize new associative amphophilic star polymers with PEO arms, to find the factors that govern the phase separation in water and that control the transfer of organic solutes to the gel phase, and to explore methods to recover the star polymers after extracting the organic solutes from water. This proposed research in theoretical physics fulfills the program objectives of advancing science by enabling leading experts in the U.S. and Bulgaria to combine complementary talents and pool research resources in areas of strong mutual interest and competence. ***

小行星9411483 这个美国-保加利亚关于“聚（环氧乙烷）缔合星星聚合物”的联合合作研究项目是纽约州立大学环境科学林业学院Johannes Smid博士研究小组和保加利亚科学院聚合物研究所Christo Tsventanov博士研究小组之间赠款的延续。该项目涉及与聚（环氧乙烷）有关的材料的合成、特性和利用，聚（环氧乙烷）是保加利亚和美国生产的一种聚合物。具体来说，在纽约州立大学锡拉丘兹校区进行的工作将涉及缔合星星聚合物与聚（环氧乙烷）臂封端的疏水部分。这种星星聚合物，目前正在我们的实验室中研究，当加入到水中时引起相分离，形成富含聚合物的凝胶相。该相对疏水性有机溶质具有高容量和亲和力。该项目旨在合成和表征具有PEO臂的新型缔合两亲性星星聚合物，以找到控制水中相分离和控制有机溶质向凝胶相转移的因素，并探索从水中提取有机溶质后回收星星聚合物的方法。这一拟议中的理论物理研究通过使美国和保加利亚的领先专家能够联合收割机互补人才并在共同感兴趣和能力强的领域汇集研究资源，实现了推进科学的计划目标。 ***
