Abstract

Pour la production de particules expansées d'une matière polymère, on met ces particules en contact avec un gaz inorganique contenant de l'azote sous pression pour en imprégner les particules, on chauffe les particules non expansées à une température supérieure au ramollissement du polymère et on les disperse dans un milieu de dispersion liquide pour obtenir une dispersion à une première pression, qui contient les particules non expansées imprégnées de gaz et ramollies, et on soumet la dispersion à une seconde pression inférieure à la première pour provoquer l'expansion des particules.
