Publication number: 20220306917Abstract: The present invention relates to a method in which an adhesive bond is brought into contact with a supercritical fluid, characterized in that the adhesive bond is based on one or more adhesives comprising crosslinked polymers, where the crosslinked polymers have at least one oxygen atom in the polymer chain and have been crosslinked via urethane bridges or —O—CH2—CH(OH)—CH2—O— bridges or molecular chains having corresponding bridges, and in that after bringing the adhesive bond into contact with the supercritical fluid, at least one of the parameters pressure, volume, amount of substance or temperature is changed such that the fluid transitions from the supercritical state into a different state, and also to the use of this method as at least a substep in a method for separating adhesive bonds of components.Type: ApplicationFiled: May 7, 2020Publication date: September 29, 2022Applicant: Evonik Operations GmbHInventors: Nicolai Kolb, Peter Altenbuchner, Gabriele Brenner, Bernhard Schleimer
