NOVEL PHOSPHONAMIDATES-SYNTHESIS AND FLAME RETARDANT APPLICATIONS

The invention relates to a group of novel compounds containing one or more amino substituted DOPO (9,10-dihydro-9-oxa-phosphaphenthren-10-oxide) moieties. The compounds were found to have good flame retardant properties and also good thermal stability, which makes them particularly suitable as flame...

Beschreibung
Zusammenfassung:	The invention relates to a group of novel compounds containing one or more amino substituted DOPO (9,10-dihydro-9-oxa-phosphaphenthren-10-oxide) moieties. The compounds were found to have good flame retardant properties and also good thermal stability, which makes them particularly suitable as flame retardant additives for various thermoplastic polymers. In particular, they can be incorporated in a polyurethane foam. La invención se refiere a un grupo de nuevos compuestos que contienen una o más porciones DOPO (9,10- dihidro-9-oxa-fosfafenan tren-10-óxido) sustituidas con amino. Se encontró que los compuestos tienen buenas propiedades de retardo el fuego y también buena estabilidad térmica, lo cual los hace particularmente adecuados como aditivos retardantes de llama para diversos polímeros termoplásticos. En particular, éstos pueden ser incorporados en una espuma de poliuretano.
