  • The Ball‐Milling Of Cellulose Fibers And Recrystallization

    The Ball‐Milling Of Cellulose Fibers And Recrystallization

    A study has been made of the effect of fine structure on the decrystallization process which results from the ball‐milling of cellulose. the rate of decrystallization is sensitive to the type of fine structure and is accelerated by the presence of moisture. the extent of chain degradation was greater in air atmosphere than in carbon dioxide.
