Abstract

LA INVENCION ES UN PROCESO PARA PREPARAR UNA COMPOSICION POLIMERICA DE CRISTAL LIQUIDO POR EJ. UNA PELICULA O FIBRA, QUE COMPRENDE EL ALINEAR UN NEUMATICO O UNA MESOFASE MONOMERICA ESMEOTICA (MONOMERO DE CRISTAL LIQUIDO) Y FOTOPOLIMERIZANDO LA MESOFASE, CARACTERIZANDOSE EN QUE LA MESOFASE ESTA ALINEADA EN UN ESTADO MULTIORIENTADO ANTES DE LA FOTOPOLIMERIZACION DE LA MESOFASE. PREFERENTEMENTE, EL ALINEAMIENTO ES UN PROCESO DE DOS O MAS ETAPAS DONDE EL PRIMER PASO COMPRENDE EL ALINEAR LA MESOFASE EN UN ALINEAMIENTO HOMEOTROPICO U HOMOGENEO UTILIZANDO TECNICAS CONVENCIONALES O LUZ POLARIZADA LINEALMENTE (ABAJO DESCRITA), Y EL SEGUNDO Y SUBSECUENTES PASOS COMPRENDEN EL ALINEAR UNA PARTE DE LA MESOFASE UTILIZANDO LUZ POLARIZADA LINEALMENTE. EN UNA SEGUNDA SINTESIS, LA INVENCION ES UN COMPUESTO DE POLIMERO DE CRISTAL LIQUIDO TAL COMO UNA PELICULA O FIBRA, CONTENIENDO CRISTALES LIQUIDOS POLIMERICOS TENIENDO MESOGENOS ALINEADOS DE ORIENTACION MULTIPLE. LA COMPOSICION ESTA PREFERENTEMENTE EN LA FORMA DE UNA PELICULA O FIBRA QUE ES AÑADIDA A UN SUBSTRATO, PARTE DE UNA CELULA DE EXHIBICION DE CRISTAL LIQUIDO, O UNA PELICULA O FIBRA POLIMERICA QUE ESTA SOLA.
