U.S.-Hungary Materials Research on Living Carbocationic Copolymerization of Select Olefins

小行星9305123 这个美国-匈牙利的研究项目“活性碳阳离子共聚的选择烯烃”是博士约瑟夫P.肯尼迪的阿克伦大学和博士蒂博尔Kelen的应用化学研究所，科苏特大学，布达佩斯。 研究人员打算通过活性碳阳离子共聚合成三个系列的新型无规共聚物：异丁烯/苯乙烯（IBu/St），异丁烯/茚（IBu/Ind）和苯乙烯/茚（St/Ind）。 在此过程中，他们将开发条件，通过动力学实验证明活性无规共聚，然后描述其产物的组成，分子量和分子量分布。 基于他们的发现，Kennedy博士和Kelen博士还将研究组成异质性作为分子量的函数。 一旦他们认为他们已经优化了无规活性IBu/ST，IBu/Ind共聚物的合成，他们将制备足够数量的有前途的共聚物产品，用于研究结构/性能相关性。 研究结果将在未来的工程应用中产生重要的新见解，如涂料和粘合剂。 这个材料研究项目实现了通过使美国的顶尖专家能够推动科学发展的计划目标。S.与匈牙利合作，联合收割机互补人才，并在共同感兴趣和有能力的领域集中研究资源。

9305123 Kennedy This U.S.-Hungary research project on "Living Carbocationic Copolymerization of Select Olefins" is between Dr. Joseph P. Kennedy of the University of Akron and Dr. Tibor Kelen of the Institute of Applied Chemistry, Kossuth University, Budapest. The researchers intend to synthesize, by living carbocationic copolymerization, three series of novel random copolymers: isobutylene/styrene (IBu/St), isobutylene/indene (IBu/Ind), and styrene/indene (St/Ind). In the process, they will develop conditions to demonstrate living random copolymerizations by kinetic experiments and then, describe the composition, molecular weight and molecular weight distribution of their products. Building upon their findings, Dr. Kennedy and Dr. Kelen also will investigate compositional heterogeneity as a function of molecular weight. Once they feel they have optimized the syntheses of random living IBu/ST, IBu/Ind copolymers, they will prepare sufficient quantities of promising copolymer products for study of structure/property correlations. Results should yield new insights of importance in future engineering applications such as coatings and adhesives. This project in materials research fulfills the program objectives of advancing science by enabling leading experts in the U. S. and Hungary to combine complementary talents and pool research resources in areas of strong mutual interest and competence.
