Abstract Details

2021, Master of Science, University of Akron, Polymer Science.
Ring-opening metathesis polymerization (ROMP) is now playing an important role in synthesizing macromolecular materials. However, existing systems for living ROMP cannot be depolymerized. Herein, 5, 6-trans-cyclobutane-fused E-cyclooctene derivatives are investigated. This system not only enables the monomer to be polymerized via living ROMP under mild, ambient conditions but also allows the resulting polymer to be depolymerized. The E-cyclooctene provides a higher ring strain for living ROMP, while the fused cyclobutane regulates the ring strain to enable depolymerization via ring-closing metathesis (RCM) depolymerization. Cyclobutane-fused E-cyclooctene monomers with two different functional groups are synthesized. The monomer functionalized with butyl esters would form a polymer melt, while the monomer with phenyl maleimide would form a glassy polymer. Polymers with narrow molecular weight distribution are gained from a preliminary polymerization. Based on the features of living ROMP, the above-mentioned monomers possess the potential to form diblock copolymers by sequential addition. The ability to be depolymerized under Grubbs’ catalyst is demonstrated as well, indicating that this system can be chemically recycled. Thus, this depolymerizable ROMP system can contribute to the global efforts to alleviate the current environmental situations.
