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.

自由基聚合中的交联：动力学和机械性能。交联的聚合物链以一种？梯子？topology.这通常在工业系统中有意或无意地发生，并影响聚合物性能。然而，交联机制知之甚少，也没有定量控制对机械性能的影响的一般方法。作为先前IREX赠款的副产品，发现了一种生长具有受控交联的聚合物的方法。该提案利用这种方法来合成具有不同交联量的聚合物，并研究其形成机制和机械性能。这具有通过聚合物改性来改进制造橡胶基材料的方法的潜力。
