SILYLATED COPOLYMERS WITH SILSESQUIOXANE GROUPS, PREPARATION METHOD THEREOF AND USE OF SAME AS HIGHLY PHOTOSTABLE LASER MATRICES

摘要

According to the invention, silsesquioxane groups are incorporated into the copolymer using monomers having a variable number (between one and 12) of polymerisable double bonds per silsesquioxane molecule. The linear cross-linked copolymers obtained have excellent optical properties and high levels of photostability, properties which render same particularly suitable for use as solid matrices for the production of laser light emitters when said matrices are provided during polymerisation with a laser dye soluble in the reaction medium and in the end copolymer obtained. The efficiency values of the resulting laser emitters are higher than those of commercial dyes, both in liquid solution and in other solid matrices. Moreover, said silylated matrices have high photostability even under extreme working conditions.
