Alkylidene functionalization produces highly recyclable and scalable polyhydroxyalkanoates Li Zhou1†‡, James H. May2,3†, Ravikumar R. Gowda1, Levi J. Hamernik2,3, Jacob K. Kenny3,4, Lili Wang1, Christopher D. Stubbs1, Ethan C. Quinn1§, Jason S. DesVeaux3,4, Katrina M. Knauer2,3, Gregg T. Beckham2,3*, Eugene Y.-X. Chen1* Recyclable polymers that can be produced at scale and readily tuned within the same polymer framework for specific properties are critical to achieving a circular materials economy. To this end, synthetic poly(3-hydroxyalkanoate)s (PHAs) have emerged as high-performance, chemically recyclable variants of biological PHAs, but their difficult monomer syntheses and suboptimal recycling efficiencies pose challenges for large-scale deployment. …
