Abstract

L'invention concerne des gels utilisés pour la formation de couches thermotropes, obtenus par exposition à une lumière riche en énergie d'un mélange contenant: a) un polymère non réticulé d'un poids moléculaire moyen en nombre Mn de 1000 à 30 000 g/mol; b) des monomères pouvant subir une polymérisation radicalaire; et c) de l'eau ou un solvant organique ou un mélange de ceux-ci.
