Thermoplastic, redox recyclable silicone–lipoamide elastomers

Lipoamide formation, from lipoic acid and aminopropylsilicones, is accompanied by ring-opening polymerization to generate thermoplastic, silicone lipoamide copolymers. The materials are readily degraded by reduction of the disulfide linkages. Silicone elastomers, renowned for their exceptional properties, have historically been thermosets. Their high stability during use compromises the ability to repurpose them at end of life. In this study, …
