Biobased High-Performance Aromatic–Aliphatic Polyesters with Complete Recyclability

Abstract: The development of high-performance recyclable polymers represents a circular plastics economy to address the urgent issues of plastic sustainability. Herein, we design a series of biobased seven-membered-ring esters containing aromatic and aliphatic moieties. Ring-opening polymerization studies showed that they readily polymerize with excellent activity (TOF up to 2.1 × 105 h–1) at room temperature and produce polymers with high molecular weight (M n up to 438 kg/mol). The variety of functionalities allows us… Show more

“…In 2021, Zhu also demonstrated the polymerization-depolymerization cycle of a series of biobased seven-membered-ring esters containing aromatic and aliphatic moieties (Scheme 27). 214 ROPs were conducted at room temperature to obtain polymers with high molecular weight (M n of up to 438 kg mol −1 ). Additionally, the resultant polymers can easily depolymerize into the starting monomer in solution or bulk.…”

“…In particular, the combination of aliphatic and aromatic monomers in one polyester leads to excellent physical and mechanical properties and a favorable cost structure. 16,17 In the present work, the polyester based on adipic acid, 1,6-hexanediol and 2,6-bis (hydroxymethyl) -pcresol, first introduced in the publication by Seithu ¨mmer et al, 18 has been applied in developed coating formulations with different hardener components, such as polyisocyanates, epoxy and melamine building blocks. Therefore, the OH functionality and OH number were calculated using different, independent methods.…”

“…Currently, to address the problem of end-of-life plastics, scientific researchers are urgently looking for the future generation of polymers and technologies that contribute to upcycling and closed-loop recycling. [7][8][9][10][11][12][13][14] Upcycling that converts end-of-life plastics to a product of higher quality or value than the original will be more acceptable by a market-oriented economy, hence improving the recycling ratio of waste plastics. [15][16][17][18][19][20] However, after the service period, the upcycled product will again face the end-oflife problem and may bring secondary pollution, leading to weak sustainability of the upcycling mode.…”
