This research proposal is concerned with the development of fundamentally new approaches to low-cost chemical technologies used in the modification of synthetic rubber products, specifically nitrile-butadiene rubbers. These strategies target selective hydrogenation or metathesis of olefinic residues in nitrile-butadiene rubber. Such modifications result in improved heat, oxidation and chemical resistance, enhanced processibility as well as decreasing the cross-linking density, hardness and modulus of the rubber thus improving mechanical properties and providing low temperature flexibility. These process improvements are key issues for material processibility and long-term stability. Moreover, such new chemical technologies will reduce the costs of production and allow the development of new and expanded product markets for nitrile-butadiene rubbers.

本研究提案涉及开发用于合成橡胶产品，特别是丁腈橡胶改性的低成本化学技术的全新方法。这些策略针对丁腈橡胶中烯烃残基的选择性氢化或复分解。这种改性导致改进的耐热性、抗氧化性和耐化学性，增强的加工性以及降低橡胶的交联密度、硬度和模量，从而改进机械性能并提供低温柔性。这些工艺改进是材料可加工性和长期稳定性的关键问题。此外，这种新的化学技术将降低生产成本，并允许开发新的和扩大的丁腈橡胶产品市场。
