Cross-linking in free-radical polymerizations: kinetics and mechanical properties

自由基聚合中的交联性：动力学和机械性能。交联型聚合物链以梯形连接在一起。拓扑学。这通常会在工业系统中有意或无意地发生，并会影响聚合物的性能。然而，人们对交联剂的作用机理知之甚少，也没有一种通用的方法来定量控制对力学性能的影响。作为之前IREX赠款的副产品，人们发现了一种生长具有受控交联性的聚合物的方法。该方案利用这种方法合成了不同交联量的聚合物，并研究了它们的形成机理和力学性能。这有可能改进通过聚合物改性制造橡胶基材料的方法。

Cross-linking in free-radical polymerizations: kinetics and mechanical properties. Cross-linked polymer chains are joined together in a ?ladder? topology. This often occurs either deliberately or accidentally in industrial systems, and affects polymer properties. However, cross-linking mechanisms are poorly understood, and there are no general means of quantitatively controlling effects on mechanical properties. As a by-product from a previous IREX grant, a means was found to grow polymers with controlled cross-linking. This proposal exploits this method to synthesize polymers with different amounts of cross-linking, and to examine their formation mechanisms and mechanical properties. This has the potential of improving means of making rubber-based materials by polymer modification.
