Abstract

UNA REACCION DIRECTA DE POLIISOCIANATOS Y POLIAMINAS SE PRODUCE DE FORMA VIOLENTA Y NO CONTROLABLE. POR ESO ES NECESARIO UTILIZAR EL POLIISOCIANATO EN FORMA BLOQUEADA. EN LOS PROCESOS CONOCIDOS HASTA AHORA NO ERA POSIBLE OBTENER LOS ADUCTOS SEMIBLOQUEADOS DESEADOS, SE OBTENIA UNA GRAN PARTE DE PRODUCTO TOTALMENTE BLOQUEADO JUNTO A POLIISOCIANATO NO REACCIONADO. LA REACCION SUBSIGUIENTE CON POLIAMINAS NO TENIA EXITO. LA OBTENCION DE POLIISOCIANATOS BLOQUEADOS CON UREA SE HIZO POSIBLE MEDIANTE EL USO DE POLIISOCIANATOS SEMIBLOQUEADOS, LOS CUALES SE FORMAN MEDIANTE ADICION DE BLOQUEADORES A POLIISOCIANATOS SOBRANTES, SEGUIDO DE UNA DESTILACION POR PELICULA FINA Y REACCION CON POLIAMINAS EN UNA PROPORCION DE GRUPOS NCO-AMINO DE 1 A 1,3:1 A 1:1. LOS POLISOCIANATOS BLOQUEADOS CON UREA SE APLICAN ESPECIALMENTE EN LACAS PUR.
