Silylated copolymers with silsesquioxane groups,nits preparation and use as high laser matricesnphotostabilityn n n The incorporation of silsesquioxane groups intoncopolymer is carried out from monomers with a numbernpolymerizable double bonds variable per molecule ofnsilsesquioxane, from one to twelve. The copolymers obtained,nlinear and crosslinked, they have excellent propertiesnoptical and high photostabilities, properties that make themnespecially applicable as solid matrices for manufacturingnof laser light emitters when they are incorporatednduring the polymerization process a soluble laser dyenin the reaction medium and in the final copolymer obtained. Thenlaser emitters thus obtained have higher efficienciesnto those obtained with commercial dyes, both in solutionnliquid, as in other solid matrices, the high being notablenphotostability presented by these silylated matrices, evennunder extreme working conditions. |
