9403566 O'Shaughnessy Theoretical research will be conducted on free radical polymerization, a method widely used in the synthesis of mass produced polymers and many types of advanced polymeric materials. The kinetics of free radical polymerization are intimately associated with the static and dynamical properties of high polymer solutions and melts through the process of termination of growing living chains by interpolymeric reaction with one another. A systematic theory of free radical polymerization will be developed based on recent advances in the theory of interpolymeric reaction rates which exploit concepts of scaling and universality. The principal quantities of practical and fundamental significance will be evaluated. This work will provide a basis for first principles models of closely related methods such as emulsion polymerization and will allow the interpretation of a large body of experimental data on the properties of polymers in the liquid and glassy state. %%% Modern analytical and computational techniques will be applied to the problem of free radical polymerization. This is one of the primary processing methods whereby polymeric materials are produced, yet it has very little theoretical basis. Thus, this research will provide a fundamental understanding of this important processing technique. ***

9403566 O'Shaughnessy将对自由基聚合进行理论研究，自由基聚合是一种广泛用于合成大规模生产的聚合物和许多类型的先进聚合物材料的方法。 自由基聚合动力学与高分子溶液和熔体的静态和动态性质密切相关，通过相互聚合反应终止生长的活性链。 自由基聚合的系统理论将根据最近的进展，利用标度和普适性的概念的互聚反应速率的理论。 将评估具有实际和根本意义的主要数量。 这项工作将提供一个基础的第一原理模型密切相关的方法，如乳液聚合，并将允许解释大量的实验数据的性质的聚合物在液体和玻璃态。 现代分析和计算技术将应用于自由基聚合问题。 这是生产聚合物材料的主要加工方法之一，但它几乎没有理论基础。 因此，这项研究将提供对这一重要加工技术的基本了解。 ***
