a–c Comparison of structural properties of FTIR (a), XPS (b), and Tg (c) before (P3) and after (H3) alcoholysis and after crosslinking (B3). d Synthetic routes and visualization of interactions in crosslinked structures. e Color projections of sign (λ2)ρ on the interaction region indicator (IRI) isosurfaces and chemical significance. f Distribution of different interactions in B3 via IRI isosurfaces. a.u. Atomic units.
