Most polymers feature a carbon polymer backbone, which poses significant challenges for degradation and chemical recycling due to the stability of C-C bonds. In contrast, polymers with backbones composed of heteroatoms are considered more degradable and recyclable. Recently, polymers with disulfide backbones have shown great promise for sustainability. This is due to their dynamic bonds, which undergo exchange reactions that enable self-healing and recycling in thermoset polymer networks. Furthermore, disulfide bonds can be reversibly cleaved into thiols and reformed through reduction and oxidation processes. In this study, we introduce a simple synthetic strategy to generate polymer backbones using the naturally derived molecule lipoic acid. The resulting poly(disulfide)s or their derivatives exhibit rubber-like properties, suggesting that this polymerization method offers a promising route for the development of eco-friendly soft materials.
