Title

(EN) Materials having a controllable degree of crosslinking

Abstract

(EN)

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.
