Abstract
This work is a study of the mechanisms by which cell wall extractable molecules intervene on its cohesion during defibrization, particularly at in situ polymers viscoelastic properties. We aim at pointing out the impact of quantitative/qualitative modulation of extractive class compounds on the chain mobility of hemicelluloses and lignin, the two major cell wall matrix amorphous polymers, and on the breaking mechanisms of the sticks at the macroscopic level.
