Abstract: A comparison has been made of the specific features of the fine structure of thermodesorption spectra of polymethylmethacrylate and its composites with nanocarbon fillers: detonation nanodiamonds, fullerene C$_{60}$, and multiwalled carbon nanotubes. The influence of the fillers on the shape of the thermodesorption spectra has been interpreted as a result of the chemical interaction between functional groups of macromolecules of the polymer matrix and active centers of filler nanoparticles.
