Caractérisation texturale par thermoporométrie et par adsorption-désorption d'azote de résines à l'état gonflé

Thermoporometry is applied to determine the porous distribution of different resins in the swollen state. In some particular cases, a comparision is possible with results of the BET-BJH methods applied to the same products dried by lyophylisation. Such a comparison enables a better understanding of the organisation and the formation of swollen systems. This determination of the porous texture of swollen resins is particularly useful for the understanding and the forecast of the general behaviour of resins.
