Abstract
Structure de polymère cellulaire microporeuse tridimensionnelle, relativement homogène. Elle comprend une multiplicité de cellules pratiquement sphériques dont le diamètre moyen est compris entre 0,5 et 100 microns environ, distribuées de façon pratiquement uniforme sur toute l'étendue de la structure, des cellules voisines étant interconnectées par des pores dont le diamètre est plus petit que celui des microcellules, le rapport du diamètre moyen des cellules au diamètre moyen des pores se situant entre 2 :1 et 200 :1 environ, les pores et les cellules étant vides et le polymère étant un polymère sysnthétique thermoplastique choisi dans le groupe constitué par des polymères oléfiniques, des polymères de condensation, des polymères d'oxydation et des mélanges de ceux-ci; on prépare ces polymères microporeux en chauffant un mélange du polymère et d'un liquide compatible pour former une solution homogène, en refroidissant cette solution dans des conditions de non équilibre thermodynamique pour déclencher une séparation de phases liquide-liquide, et en poursuivant le refroidissement jusqu'à ce que la matière acquiere une résistance suffisante à la manipulation. Application : produits de polymères microporeux qui contiennent des quantités relativement grandes de liquides fonctionnellement utiles en se comportant comme des solides.
