Abstract: The molecular compositions of products formed during the friction of polymers [poly(methyl methacrylate), polystyrene] in both symmetric (same materials) and asymmetric (different materials) polymer-on-polymer friction pairs have been determined by using mass spectrometry. In addition to monomers, which are formed during friction as a result of the depolymerization of the corresponding free macroradicals, the mass spectra reveal new products. The formation of these products is explained by the interaction of monomers with hydrogen molecules, which are also formed in the contact zone.
