Abstract

PROCEDIMIENTO PARA LA OBTENCION DE POLIISOCIANATOS CON ESTRUCTURA BIURET. CONSISTENTE EN HACER REACCIONAR CANTIDADES EN EXCESO DE DIISOCIANATOS ALIFATICOS (1,6-DIISOCIANATOHEXANO) CON AGENTES DE BIURETIZACION. SIENDO LOS AGENTES DE BIURETIZACION ACIDOS ACETICOS A-A-A-TRISUSTITUIDOS, QUE NO CONTENGAN GRUPOS REACTIVOS CON RESPECTO AL GRUPO ISOCIANATO, APARTE DEL GRUPO CARBONILO, Y AGUA, EN UNA PROPORCION MOLAR DE 1: 0-2,5. SE EMPLEAN COMO DISOLVENTES ETERES, ESTERES, ETERES-ESTERES, CETONAS, NITRILOS O SULFONAS. EL PROCESO SE LLEVA A CABO A UNA TEMPERATURA COMPRENDIDA ENTRE 20 Y 160 C (PREFERENTEMENTE 60-140 C), NORMALMENTE A PRESION NORMAL AUNQUE TAMBIEN PUEDE REALIZARSE BAJO PRESIONES COMPRENDIDAS ENTRE 1 Y 50 BAR (PREFERENTEMENTE 1-5 BAR). DE APLICACION EN LACAS QUE REQUIERAN SOLIDEZ A LA LUZ Y ESTABILIDAD FRENTE A LOS AGENTES ATMOSFERICOS CON MATENIMIENTO DE BRILLO.
