Olefin metathesis is one of the most widely used methods for the formation of carbon-carbon double bonds. Acyclic diene metathesis (ADMET) polymerization has been extensively used in the synthesis of precision polymers by using well-defined monomers to form unique polymer morphologies with intriguing physical properties. Traditional ADMET polymerization cannot be used to synthesize block or alternating polymers. Selective acyclic diene metathesis (SADMET) polymerization synthesizes a polymer with non-reactive backbone double bonds by sequentially reacting electron deficient α,ω-dienes with the reactive internal olefin bonds to form block and alternating polymers. To date, only acrylates have been widely utilized as the electron deficient monomers in SADMET polymerizations. This project targeted the incorporation of new monomer types and expanded the types of polymers synthesized via SADMET polymerizations. However, functional groups with high melting points still cannot be used by either polymerization technique as current ruthenium-based catalysts are limited by their thermal stability. A model ADMET polymerization was devised using new high temperature catalysts and tested over various temperatures and times. Molar mass data have been reported for the first precision ketone polymers synthesized via high temperature ADMET polymerization in under an hour.
