Abstract

UN PROCEDIMIENTO PARA OBTENER UN PLASTICO DE POLIURETANO, QUE TIENE PROPIEDADES FOTOCROMICAS, CARACTERIZADO PORQUE EL PROCEDIMIENTO COMPRENDE, EN UNA PRIMERA ETAPA, LA INCORPORACION DE UN COMPUESTO FOTOCROMICO DE EXCISION REVERSIBLE A POR LO MENOS UN COMPUESTO DE DIISOCIANATO, O POR LO MENOS UN POLIOL O UNA MEZCLA DE DIISOCIANATO Y UNO O MAS POLIOLES O A CUALQUIER OTRO COMPONENTE DE UNA MEZCLA QUE, CUANDO SE POLIMERIZA, PRODUCE UN POLIURETANO; COMBINAR LA MEZCLA DE LA PRIMERA ETAPA CON CUALESQUIERA OTROS COMPONENTES NECESARIOS PARA HACER POSIBLE QUE TENGA LUGAR LA POLIMERIZACION; Y POLIMERIZAR LA MEZCLA RESULTANTE PARA FORMAR UN POLIURETANO QUE INCORPORA DICHO COMPUESTO FOTOCROMICO. LOS PLASTICOS DE POLIURETANO FOTOCROMICO DE LA INVENCION SON UTILES COMO CAPAS DE INTERMEDIOS DE LAMINADOS DE VIDRIO O PLASTICOS PARA APLICACIONES ARQUITECTONICAS O PARA EN VENTANAS DE VEHICULOS O GUARDILLAS.
