Materials made from covalently crosslinked polymer networks are ubiquitous in everyday life but are difficult to process at the end of their life cycle. New materials designed with sustainability in mind will play a critical role in reducing the detrimental effects of plastic waste build-up. Functionalized triazines such as 1,3,5-triazine-2,4,6-triamine (melamine), hexamethylol melamine (HMM), and hexa(methoxymethyl)melamine (HMMM) are key components of robust thermosets, adhesives, and coatings. We combine HMM and HMMM with an alkoxysilane to produce transparent thermosets with remarkable glass adhesion. The dynamicity of silyl ether bonds in the network makes the materials susceptible to methanolysis, enabling the recovery of HMMM and the substrate. A combination of solution- and solid-phase techniques are used to elucidate both gelation and degradation pathways.
