The primary objective of this U.S.-Hungary project between Dr. Otto Vogl of Polytechnic University and Dr. Ferenc Tudos of the Hungarian Central Research Institute for Chemistry is to examine the mechanisms of oxidation of polyolefins, particularly head-to-head poly (vinyl chloride). To do this the researchers will study the thermal vs. photooxidation of well characterized head-to-head and head-to-tail polymers, which they previously synthesized. Their comparisons will involve oxidation of these polymers in solution, in the melt, and in the glassy (amorphous) state. Results should contribute to our knowledge of a broader spectrum of polymer structures which in turn may establish a basis for developing a basic scheme for degradation of polymers with carbon-carbon backbone chains. This project in polymer research fulfills the program objective of advancing scientific knowledge by enabling leading researchers in the United States and Eastern Europe to combine complementary talents and pool research resources in areas of strong mutual interest and competence.

美国的主要目标是-匈牙利理工大学的Otto Vogl博士和匈牙利中央化学研究所的Ferenc Tudos博士之间的项目是研究聚烯烃的氧化机制，特别是头对头聚氯乙烯。为了做到这一点，研究人员将研究他们以前合成的具有良好特征的头对头和头对尾聚合物的热氧化与光氧化。他们的比较将涉及这些聚合物在溶液中，熔体中和玻璃态（无定形）的氧化。结果应有助于我们的知识，更广泛的聚合物结构，这反过来又可能建立一个基础，开发一个基本的计划与碳-碳主链的聚合物降解。该聚合物研究项目通过使美国和东欧的领先研究人员能够联合收割机互补人才，并在相互感兴趣和有能力的领域汇集研究资源，实现了推进科学知识的计划目标。
