The thermal behavior of chitosan (CS)/natural rubber latex (NRL) blends has been studied by thermogravimetry (TG) and differential
scanning calorimetry (DSC). Decomposition behavior of CS changes with the addition of NRL. The effect of blend composition
on the amount of residue remaining at various temperatures has been studied. Activation energies of degradation have been
calculated using Horowitz-Metzger equation. From the activation energy values, it is found that among the series of the blend
compositions, CS15NRL85 exhibits better thermal stability. DSC studies reveals that the CS/NRL blends are thermodynamically incompatible. This is
evident from the presence of two glass transitions, corresponding to CS and NRL phases in the blend.
