Acyclic diene metathesis polymerization was demonstrated late in 1988 by the authors using metathesis catalysts free of Lewis acids (Schrock's catalyst). Aliphatic and aromatic homo- and copolymers have thus been made. Monomer structure/reactivity relationships have been established; and unsaturated polymers containing functional groups have been prepared, including unsaturated polyethers, polyketones, polyesters, polycarbonates, and polycarbosilanes. An air-stable metathesis catalyst and oligomers of metal-containing polymers have been prepared. In this research, the polymer chemistry associated with the reaction will be explored by evaluating the influence of nitrogen- and sulfur-containing functional groups; and by synthesizing chiral polymers, more elaborate silicon-containing polymers, and perfectly functionalized telechelic oligomers. Attempts will be made to advance this research by synthesizing tailored catalyst systems possessing a high degree of thermal stability. This Materials Synthesis and Processing grant is jointly funded by the Division of Materials Research and the Division of Chemistry.

无环二烯复分解聚合在2005年后期被证明。 1988由作者使用不含刘易斯酸的复分解催化剂 （Schrock催化剂）。 脂肪族和芳香族均聚物和共聚物 就这样做了。 金属结构/反应性关系 已建立;和不饱和聚合物， 已经制备了官能团，包括不饱和的 聚醚、聚酮、聚酯、聚碳酸酯和 聚碳硅烷。 空气稳定的复分解催化剂和低聚物 的含金属聚合物。 在本研究中， 将探索与反应相关的聚合物化学 通过评估含氮和含硫的影响， 官能团;通过合成手性聚合物， 精细的含硅聚合物， 遥爪低聚物。 将努力推动这一点 研究通过合成定制的催化剂体系， 高度热稳定性。 该材料合成和加工补助金由以下机构共同资助： 材料研究部和化学部。
