Beschreibung
Zusammenfassung:	Provided are compositions including a reaction product of a polymerizable mixture containing a multifunctional epoxy component; a polysulfide component including at least one disulfide bridge; and a base having a sufficiently high basicity to deprotonate an -SH group of the polysulfide component. The reaction product is in a form of a polymeric matrix. The composition can be attached to an object, for instance located between two objects. Additionally, methods of making articles including the composition, bonding two objects together, and aiding debonding of two objects, are provided. L'invention concerne des compositions comprenant un produit de réaction d'un mélange polymérisable contenant un composant époxy multifonctionnel ; un composant polysulfure comprenant au moins un pont disulfure ; et une base ayant une basicité suffisamment élevée pour déprotoner un groupe -SH du composant polysulfure. Le produit de réaction se présente sous la forme d'une matrice polymère. La composition peut être fixée à un objet, par exemple située entre deux objets. De plus, l'invention concerne des procédés de fabrication d'articles comprenant la composition, la liaison de deux objets ensemble, et l'aide au décollement de deux objets.
