Beschreibung
Zusammenfassung:	Methods for upcycling crosslinked sodium polyacrylate to pressure sensitive adhesives via (a) mechanochemical chain-shortening and esterification or (b) esterifying with high conversion with a Fischer esterification process are disclosed. Also disclosed is a pressure sensitive adhesive prepared by the disclosed methods and articles comprising the pressure sensitive adhesive, including, but not limited to, pressure sensitive tape, a bandage, a label, note pads, a decal, a stamp, an envelope, a sticker, packaging, automobile trim, and a film. L'invention concerne des procédés de valorisation de polyacrylate de sodium réticulé en adhésifs sensibles à la pression par (a) raccourcissement mécano-chimique de chaîne et estérification ou (b) estérification à conversion élevée par un procédé d'estérification de Fischer. L'invention concerne également un adhésif sensible à la pression préparé par les procédés et articles décrits comprenant l'adhésif sensible à la pression, y compris, mais pas exclusivement, un ruban sensible à la pression, un bandage, une étiquette, des blocs-notes, une décalcomanie, un timbre, une enveloppe, un autocollant, un emballage, une garniture d'automobile, et un film.
