Functional materials having a controllable viscosity or reversible crosslinking via aza Diels-Alder reactions with bishydrazones or conjugated bis-Schiff bases

摘要

The present invention relates to innovative materials which are reversibly crosslinkable by means of a thermoreversible mechanism and/or whose viscosity is reversibly adjustable. Through the use of bishydrazones or conjugated bis-Schiff bases as diene components in aza-Diels-Alder reactions, functional materials are generated that feature controllable viscosity and/or reversible crosslinking.
