Abstract

Procédé de préparation de mousses réticulées de polyéthylène chloré. On prépare ces mousses par irradiation d'un mélange d'un agent moussant, décomposable thermiquement, et d'un polyéthylène chloré, de haute densité, comportant de 25 à 48 % de chlore chimiquement combiné et ayant un module de flexion à 25 degrés C de moins de 1 050 kg/cm**2, avec un rayonnement ionisant de 1 à 10 mrads, tout en maintenant le mélange à une température inférieure à la température de décomposition de l'agent moussant, ce mélange étant ensuite mis en contact avec un milieu de transfert de chaleur. Permet l'obtention de mousses réticulées, molles, flexibles, à cellules fermées de polyéthylène chloré de haute densité.
