Abstract

L'invention concerne un cristal liquide capable de polymérisation en phase mésomorphe et un polymère solide ayant conservé une grande partie des propriétés anisotropes du cristal liquide. On cherche à obtenir des couches de très faible épaisseur (moins de 100 microns). Suivant l'invention, on effectue la synthèse d'un monomère de formule :
