Key Points

  • This research aims to explore the conversion of triacetic acid lactone into a renewable monomer for circular polymer applications.
  • Developed a multistep catalytic strategy
  • Utilized bio-derived triacetic acid lactone (TAL)
  • Synthesized poly(α-methylene-δ-caprolactone) (PMCL)
  • PMCL exhibits higher heat resistance compared to traditional PMMA
  • Demonstrated chemical recyclability of the synthesized polymer
  • Provides a sustainable alternative for polymer applications

Abstract

We report a multistep catalytic strategy for converting bio-derived triacetic acid lactone (TAL) into poly(α-methylene-δ-caprolactone) (PMCL), a sustainable PMMA analogue with higher heat resistance and demonstrated chemical recyclability.
