Cellulose produced by different processes. (Spray dried and comminuted) have been characterised by low temperature (77K) nitrogen adsorption to determine the specific surface areas, micro‐ and meso‐porosities together with the thermodynamic properties of the Polanyi surface potential and heat (enthalpy) of adsorption. These physico‐chemical and thermodynamic parameters are then correlated with the physico‐mechanical properties of compactability to indicate the bonding strenghts of microcrystalline and microfine celluloses.
