Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

    Polymerization Kinetics of Cyclic Esters by Metal Alkoxide Complexes and Catalytic Decarbonylation of Bio-Derived Carboxylic Acids to Commodity Alkenes
    (2014-05) Miranda, Maria
    Plastic materials are an integral part of modern life; however, nearly every plastic, or polymer, is derived from petroleum resources, which are non-sustainable, non-degradable, and can be toxic to humans and the environment. Developing methodologies to synthesize and characterize alternative materials that are degradable, safe, and sustainable has therefore been a vibrant research area. This thesis describes two approaches towards the development of sustainable polymers and monomers (the building blocks from which polymers are made). The first aims to understand the fundamental mechanistic details of metal-catalyzed ring-opening polymerization of renewable cyclic ester monomers to degradable polyesters. The second targets the catalytic synthesis of common petroleum-based monomers from sustainable and biomass-derived carboxylic acids.
