Measurements of chemiluminescence under conditions of periodic temperature changes (temperature cycling) may well be related to the changes of the polymerization degree for cellulose degraded under comparable conditions in isothermal mode. The subsequent deceleration of the degradation process, as seen from the analysis of a series of temperature cycles, has been demonstrated. A second order non‐isothermal model of cellulose degradation distinguishing a faster and a slower degrading component in cellulose has been used to fit the experimental data. © 2000 Society of Chemical Industry
