Abstract
Official abstract text for this publication.
The present invention relates to innovative materials which can be crosslinked by means of two different crosslinking mechanisms, the first crosslinking mechanism being an irreversible crosslinking. The second crosslinking mechanism is a thermoreversible mechanism. As a result of this thermoreversible change in the arc length, properties of the crosslinked material can be decisively changed and controlled, including flexibility, elasticity and other mechanical properties, but also chemical properties, the gas permeability and vapor permeability and storage capacity of the network. In this way it would be possible, for example, to store energy sources such as fuels.
First claim
Opening claim text (preview).
The invention claimed is: 1. A partially reversibly crosslinkable formulation which is crosslinkable by: (A) a Diels-Alder reaction or a hetero-Diels-Alder reaction, said reactions activated at room temperature such that crosslinking is reversible to an extent of at least 50% at a higher temperature; and (B) a crosslinking reaction different than the Diel-Alder reactions (A), the crosslinkable formulation comprising: a component A comprising at least two dienophilic double b…
