Title (EN) READILY SHAPEABLE XEROGELS HAVING CONTROLLABLY DELAYED SWELLING PROPERTIES
(FR) XEROGELS POUVANT ETRE FACONNES ET POSSEDANT DES PROPRIETES DE GONFLEMENT A RETARD CONTROLABLE
Abstract: front page image
(EN)Hydrogels are described which have delayed swelling properties. A hydrogel is formed by reacting a hydrophilic monomer, a first crosslinker, and a second crosslinker. The first crosslinker defines the volume expansion of the hydrogel in an aqueous environment, and the second crosslinker, which is biodegradable, can modulate the swelling rate of the hydrogel in aqueous solution. In its dry state, the hydrogel (xerogel) is flexible and elastic. It can also be cut with a knife or scissors, or molded or shaped by hand. The ready shapeability of the xerogel by trimming or compression affords a superior hydrogel for medical applications.
(FR)L'invention concerne des hydrogels possédant des propriétés de gonflement retard. On obtient un hydrogel par réaction d'un monomère hydrophile, d'un premier agent de réticulation et d'un deuxième agent de réticulation. Le premier agent de réticulation définit l'expansion volumique de l'hydrogel dans un milieu aqueux et le deuxième agent de réticulation, biodégradable peut moduler la vitesse de gonflement de l'hydrogel dans une solution aqueuse. A l'état sec, cet hydrogel (xérogel) est souple et élastique. On peut aussi le découper avec un couteau ou des ciseaux ou le mouler ou le façonner à la main. Les capacités de modification de forme de ce xérogel par découpage de compression permettent d'obtenir un hydrogel supérieur pour des applications médicales.
