The literature contains a number of examples of the successful application of the Arrhenius equation to multicomponent systems where the principal component is paper. In these studies, the logarithms of rate constants for physical or chemical properties are plotted vs. 1/T to give straight lines. This approach has been applied to systems as diverse as rosin sized papers and clay filled papers. However, for some systems, physical strength measurements -- e.g., folding endurance (TAPPI T-511su-69) and breaking strength (TAPPI T-404ts-66) -- demonstrate the independent aging of the components leading to complex, nonlinear Arrhenius plots. Examples from studies of various adhesive-paper model systems are discussed. See also AATA 15-389.
