Abstract
Theoretical and experimental results are presented, on the basis of which it is concluded that the structure of cross-linked elastomers is, for thermodynamic reasons, sets of tangles-globules consisting of chain segments of the same lengths. The deformation of such a system proceeds unaffinically by successive destruction of structural elements with increasingly high elastic modules determined by the growing molecular weights of the chains that make up the structural elements. The above method of "Equilibrium Thermomechanical Analysis" (ETMA) for cross-linked elastomers confirms the existence of the above structures and allows quantifying a number of physicochemical and operational properties that are not determined by other methods depending on the compositions (formulations) of elastomers and their stress-strain equilibrium states.
