The primary objective of this U.S..Hungary cooperative research project between Dr. Joseph P. Kennedy of the University of Akron and Dr. Tibor Kelen of the Kossuth Lajos University, Debrecen, Hungary is to study the effects of process variables in the preparation of telechelic polyisobu>tylenes. Relative telechelic polymer yield, molecular weight and molecular weight distribution will be determined through fundamental kinetic studies. Results should contribute to a second objective of synthesising "perfect" and mixed polyisobutylene.based rubbery networks which may be suitable for studying a number of follow.on questions pertaining to the theory of rubber elasticity and bimodal networks. This project in polymer research 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 research resources in areas of strong mutual interest and competence. In addition to new knowledge of elastomeric networks, collaborative efforts under this project are also expected to yield sufficient inventories of new polymers for use by polymer physicists and engineers in subsequent research.

阿克伦大学的 Joseph P. Kennedy 博士和匈牙利德布勒森 Kossuth Lajos 大学的 Tibor Kelen 博士之间的这个美国匈牙利合作研究项目的主要目标是研究制备遥爪聚异丁烯过程中工艺变量的影响。 相对遥爪聚合物产率、分子量和分子量分布将通过基础动力学研究来确定。 结果应有助于合成“完美”和混合的聚异丁烯基橡胶网络的第二个目标，该网络可能适合研究与橡胶弹性和双峰网络理论有关的许多后续问题。 该聚合物研究项目通过使美国和东欧的领先专家能够在共同感兴趣和能力强的领域结合互补人才并汇集研究资源，实现了推进科学知识的计划目标。 除了弹性体网络的新知识之外，该项目下的合作预计还将产生足够的新聚合物库存，供聚合物物理学家和工程师在后续研究中使用。
