Abstract

Se producen espumas de poliéster poliuretano flexibles, de bajo aspecto nuboso u opaco al hacer reaccionar, a) poliisocianatos, con b) poliésteres que contienen por lo menos dos grupos hidroxilo y que tienen un peso molecular en el intervalo de 400 a 100,000 en presencia de c) agua y/o compuestos orgánicos fácilmente volátiles como agentes de soplado en el que antes de reaccionar, los poliésteres se han sometido a destilación continúa durante un tiempo de retención promedio de 2 a 600 s, a una temperatura de 160º a 250ºC, y bajo una presión de 0.05 a 10mbar. Opcionalmente, la mezcla de reacción puede contener d) compuestos que contienen por lo menos dos átomos de hidrógeno activos y que tienen un peso molecular en el intervalo de 32 a 400 como agentes para extender la cadena y reticulantes, y/o e) auxiliares y aditivos conocidos per se. Estas espumas de poliéster poliuretano de bajo aspecto nuboso u opaco son extremadamente adecuadas para uso en vehículos, preferiblemente automóviles.
