DOI: 10.1039/d0py00342e
Abstract: The present study explores a broad range of stoichiometry, with the [epoxy]/[acyl] ratio ranging from excess to unity for commercial diepoxide/sebacic acid vitrimer formulations, with 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) used as the catalyst. In particular, it investigates… read more here.
