Abstract

Acyclic diene metathesis (ADMET) polymerization, a type of olefin cross metathesis, is a step-growth and condensation polymerization that can be used to synthesize hydrocarbon polymers with diverse functional groups. Traditional ADMET with symmetric α,ω-dienes is not selective and can only form homopolymers or statistical copolymers. Changing to monomers with acrylate functional groups allows selective reactivity to form block and alternating polymers. In this project, we want to explore other functional groups that result in selective reactivity to form advanced polymer architectures via what we have termed selective acyclic diene metathesis (SADMET) polymerization. Developing new functionalized monomers for SADMET polymerization allows for the synthesis of precision alternating copolymers with a variety of backbone chemistries, pendant groups, and tacticity. In addition, the steric effect around the monomers double bonds was examined with the goal of finding more monomers that can be used to make block or alternating polymers via SADMET polymerization. With this control over the polymer chain, the newly engineered polymers could be applied to ion transport, drug delivery, and polymer self-assembly
