Beschreibung
Zusammenfassung:	This disclosure relates generally to adhesives and particularly to reversible adhesives. This disclosure further relates to generally adhesive articles and particularly to wound dressings comprising such adhesives. The adhesive comprises a core and a shell comprising at least two components. One of the components of the shell comprises a polymer formed by reacting a monomer of a thermally reversible polymer and the other component comprises a polymer formed by reacting a monomer of a polymer of a pressure sensitive adhesive. The wound dressing comprises a substrate and the reversible adhesive, forming a reversible wound dressing. Such wound dressings are particularly suitable for treatment of damaged sensitive tissue, for example wounds formed on a fragile skin. La présente invention concerne des adhésifs et en particulier des adhésifs réversibles. L'invention concerne en outre des articles adhésifs et en particulier des pansements comprenant de tels adhésifs. L'adhésif comprend une partie centrale et une enveloppe comprenant au moins deux composants. Un des composants de l'enveloppe comprend un polymère obtenu en faisant réagir un monomère d'un polymère thermiquement réversible et l'autre composant comprend un polymère obtenu en faisant réagir un monomère d'un polymère adhésif sensible à la pression. Le pansement comprend un substrat et l'adhésif réversible, formant un pansement réversible. De tels pansements sont particulièrement appropriés dans le traitement de tissus endommagés sensibles, par exemple des plaies formées sur une peau fragile.
