Title

(EN) MATERIALS HAVING A CONTROLLABLE DEGREE OF CROSSLINKING

(FR) MATERIAUX A DEGRE DE RETICULATION POUVANT ETRE DETERMINE

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 vapour
permeability and storage capacity of the network. In this
way it would be possible, for example, to store energy
sources such as fuels.
