WATER-ABSORBENT ADHESIVE COMPOSITIONS AND ASSOCIATED METHODS OF MANUFACTURE AND USE

An adhesive composition is provided that is water-insoluble yet water-absorbent, i.e., capable of absorbing up to 15 wt.% water or more. The composition is composed of a film-forming hydrophilic polymer with at least one linear segment having a plurality of recurring polar groups along the polymer b...

Zusammenfassung:	An adhesive composition is provided that is water-insoluble yet water-absorbent, i.e., capable of absorbing up to 15 wt.% water or more. The composition is composed of a film-forming hydrophilic polymer with at least one linear segment having a plurality of recurring polar groups along the polymer backbone, a complementary multifunctional polymer with a plurality of recurring functional groups that noncovalently bind to the polar groups on the film-forming polymer, and a plasticizer. A method for manufacturing the adhesive composition is provided as well. L'invention concerne une composition adhésive insoluble dans l'eau mais pouvant absorber l'eau, notamment pouvant absorber jusqu'à 15 % en poids d'eau environ. La composition de l'invention est constituée d'un polymère hydrophile formant film présentant au moins un segment linéaire comportant une pluralité de groupes polaires récurrents le long du squelette polymère, un polymère multifonctionnel complémentaire comportant une pluralité de groupes fonctionnels récurrents se liant de manière covalente aux groupes polaires situés sur le polymère formant film, et un plastifiant. L'invention concerne également une méthode pour fabriquer cette composition adhésive.
