Abstract

METODO DE PREPARACION DE DISPERSIONES DE POLIUREAS Y POLIHIDRAZODICARBONAMIDAS. CONSISTE EN LA REACCION EN CONTINUO DE POLIISOCIANATOS ORGANICOS CON POLIAMIDAS QUE CONTIENEN GRUPOS AMINO PRIMARIOS O SECUNDARIOS O HIDRAZIDAS EN PROPORCION EQUIVALENTE DE LOS COMPONENTES ENTRE 1,051:1 A 1,50:1, EN POLIETERES DE PESO MOLECULAR ELEVADO, QUE CONTIENEN COMO MINIMO UN GRUPO HIDROXILO. LA REACCION SE LLEVA A CABO EN UN MEZCLADOR DE FLUJO DE PASO CONTINUO CON TIEMPO DE RESIDENCIA MEDIO INFERIOR A 10 MINUTOS, Y EL PRODUCTO FORMADO SE RECOGE A UNA TEMPERATYRA ENTRE 50JC Y 150JC. ESTAS DISPERSIONES TIENEN APLICACIONES PARA LA FABRICACION DE POLIURETANOS, EMPLEADOS EN LA INDUSTRIA DEL AUTOMOVIL.
