“…Chemical recycling to monomers represents an attractive strategy for circular polymer economy. [6][7][8][9][10][11][12][13][14] Ringopening polymerization (ROP) provides the foundation for chemically recycling to monomers of the producing polymers via ring-close depolymerization. [6] In addition, ROP of cyclic monomers has been shown to synthesize polymers with high-level control of microstructure and desired properties.…”

The development of innovative synthetic polymer systems to overcome the trade‐offs between the polymer's depolymerizability and performance properties is in high demand for advanced material applications and sustainable development. In this contribution, we prepared a class of aromatic cyclic esters (M1–M5) from thiosalicylic acid and epoxides by facile one‐pot synthesis. Ring‐opening polymerization of Ms afforded aromatic polyesters P(M)s with high molecular weights and narrow dispersities. The physical and mechanical properties of P(M)s can be modulated by stereocomplexation and regulation of the side‐chain flexibility of the polymers, ultimately achieving high‐performance properties such as high thermal stability and crystallinity (Tm up to 209 °C), as well as polyolefin‐like high mechanical strength, ductility, and toughness. Furthermore, the functionalizable moieties of P(M)s have driven a wide array of post‐polymerization modifications toward access to value‐added materials. More importantly, the P(M)s were able to selectively depolymerize into monomers in excellent yields, thus establishing its circular life cycle.

“…Chemical recycling of polymers into monomers or monomer precursors offers a feasible solution to reduce fossil fuel use and relieve the environment pressure caused by the accumulation of plastic waste. [60][61][62][63][64] PEAs contain both ester and amide linkages in their backbones, and they are expected to chemically degrade into small molecules with either alkaline or acidic catalysts through the hydrolysis of the ester bonds. Degradation of P1a (Table 1) and P2a (Table S1 †) was performed in DMSO-d 6 /D 2 O at 30 °C using NaOD as the catalyst.…”

“…27,28 Importantly, the ring-closing depolymerization of these systems typically requires a catalyst; without the catalyst, the polymers are in a kinetic trap. 29 The mechanism of catalytic depolymerization has enabled high thermal stability to be achieved when the catalyst is removed from the system. Meanwhile, CRM can occur under mild conditions by introducing an appropriate catalyst.…”
