Abstract

Des particules de résine préexpansées sont produites en dispersant des particules à nucléocellules dans un milieu dispersant en récipient fermé, que l'on chauffe jusqu'à température de ramollissement ou plus et que l'on maintient sous pression à cette température, avec un gaz inorganique, puis qu'on libère, ainsi que le milieu, en atmosphère à pression inférieure pour les amener à subir une expansion.
