Abstract

DICHAS CONVERSIONES SE REALIZAN BAJO LA INFLUENCIA DE RADIACION POR EXPOSICION DEL COMPUESTO DE TAQUISTEROL Y EL DE TRANS-VITAMINA, RESPECTIVAMENTE DISUELTOS EN UN DISOLVENTE APROPIADO EN PRESENCIA DE UN FOTOSINTETIZADOR POLIMERICO QUE CONSISTE EN UNA CADENA DE POLIMERO (EJE. CENTRAL) QUE COMPRENDE UN ENLACE COVALENTEMENTE SINTETIZADO APROPIADO PARA LA CONVERSION FOTOQUIMICA, PARA ILUMINAR CON UNA LONGITUD DE ONDA DE APROX. 300 A 1.000NM, Y PARA SU AISLAMIENTO DEL COMPUESTO DE PREVITAMINA D Y DE CIS-VITAMINA D RESPECTIVAMENTE PARA LOS CUALES UN FOTOSINTETIZADOR ES USADO EN LA CADENA DE POLIMERO, LA CUAL HA SIDO SELECCIONADA DEL GRUPO QUE CONSISTE EN UNA CADENA POLIETER, UNA CADENA DE POLIMERO QUE CONTIENE GRUPOS AMINO Y UNA CADENA DE BLOQUES DE COPOLIMERO QUE COMPRENDE SEGMENTOS DE POLIETER Y/O SEGMENTOS DE POLIMERO QUE CONTIENEN GRUPOS AMINAS, DE MANERA QUE EL FOTOSINTETIZADOR POLIMERICO DISUELVE EN EL SISTEMA DISOLVENTE DURANTE LA EXPOSICION A LA RADIACION PERO CUALQUIERA SE PRECIPITAEN FRIO DESDE LA SOLUCION Y PUEDE SER SEPARADO, O EN CASO DE QUE DICHA CADENA DE POLIMERO COMPRENDA GRUPOS AMINAS PUEDE SER PROTONADOS CON UNA SUSTANCIA ACIDA APROPIADA Y ELIMINADOS EN UN TRATAMIENTO POSTERIOR. LA INVENCION TAMBIEN TRATA UN FOTOSINTETIZADOR PARA SER USADO EN DICHO METODO.
