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.
