Abstract

L'invention concerne un matériau anti-conglutination qui possède une fonctionnalité permettant une fixation fiable de celui-ci à un tissu biologique et dans lequel l'adhésivité à un tissu et la biodégradabilité sont améliorées. Le matériau anti-conglutination possède une couche de support soluble dans l'eau qui contient un polymère soluble dans l'eau et qui présente une épaisseur de 1 à 1 000 µm et une couche anti-conglutination qui contient un polymère biodégradable et qui présente une épaisseur de 1 à 1 000 µm, le polymère biodégradable possédant une structure dans laquelle un polyalkylène glycol ramifié comprenant trois à huit groupes hydroxyle terminaux par molécule et un acide polyhydroxyalcanoïque sont liés, et la proportion de la masse du polyalkylène glycol ramifié par rapport à la masse totale est de 1 à 30 %.
