Abstract

Procédé perfectionné pour remédier aux propriétés collantes de la surface d'un hydrogel d'un polymère hydrosoluble du type polymère d'acrylamide. On applique sur la surface de l'hydrogel un revêtement d'un acide gras supérieur tel que l'acide stéarique ou d'un sel de métal alcalin d'acide gras supérieur. Le procédé selon l'invention permet en particulier de faciliter le séchage des hydrogels du type en question, en empêchant le collage sur les parois des appareils.
