Sugar‐Based Alternating Copolymers via Photoinduced Radical Copolymerization of Levoglucosenone and Vinyl Ethers

Abstract

Abstract Herein, we report the synthesis of a library of 17 sugar‐based alternating copolymers via photoinduced radical copolymerization of naturally occurring levoglucosenone (LGO) and a broad range of commercially available vinyl ethers. This strategy leverages renewable feedstocks and enables precise control over copolymer sequence, affording materials with excellent thermal stability, tunable glass transition temperature ( T g ), and on‐demand degradability. The resulting sugar‐based materials exhibit superior adhesive strength compared to commercial benchmarks such as commercial polyurethane adhesive and ethylene‐vinyl acetate (EVA). Postpolymerization modifications further facilitate the preparation of fluorescent materials and graft semiconducting polymers, expanding the functional versatility of these sugar‐based alternating copolymers.
