Abstract: L'invention concerne un procédé de préparation d'un hydrogel à rétention gastrique de type gonflant destiné à une intervention contre l'obésité, qui appartient aux domaines techniques des matériaux du type hydrogel et de la thérapie physique par intervention contre l'obésité. L'hydrogel est conçu comme un double réseau pour avoir une bonne performance de gonflement et une bonne stabilité mécanique. Un premier réseau peut gonfler dans les sucs gastriques et permet d'atteindre le but d'une intervention contre l'obésité par occupation du volume de l'estomac et réduction de la quantité de la prise alimentaire. Un second réseau est utilisé pour compenser la dégradation de propriétés mécaniques provoquée par le gonflement du premier réseau. Le second réseau peut se former spontanément dans les sucs gastriques. En d'autres termes, l'hydrogel peut former un nouveau réseau tout en gonflant, ce qui permet de maintenir la densité des chaînes moléculaires et la stabilité mécanique. Les exigences liées au dispositif instrumental impliqué dans le procédé sont simples. Le procédé de préparation est simple, régulable et facile à mettre à l'échelle. L'hydrogel préparé peut être administré par voie orale, gonfle rapidement dans les sucs gastriques et a un taux de gonflement supérieur à 1000 %, et est retenu dans l'estomac pendant plus de 15 jours, période pendant laquelle les propriétés mécaniques sont maintenues stables. Après une rétention à long terme, l'hydrogel peut être biodégradable, ce qui permet d'assurer la sécurité de l'évacuation de l'hydrogel.
