Abstract:
A polymer is made by polymerization of CBDA-4 monomers with a glycerol linker through a condensation reaction. The resulting polymer is thermally cleavable having a plurality of CBDA-4 monomers linked with the glycerol linkers, making it recyclable when heated and degraded. The resulting intermediate material can be hydrolyzed back to initial starting material for synthesizing CBDA-4 monomers.
