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.
Synthesis of new dibenzo[c.e][1,2]oxaphosphorine 2-oxide containing diols based on diethanolamine
Different approaches were applied to obtain new diol compounds based on dibenzo[c.e][1,2]oxaphosphorine 2-oxide (DOPO, 1) and diethanolamine (DEolA). Of four processes investigated, a four-step synthesis of 1 containing propionic acid amide of DEolA proved to be the most efficient one. In addition, the intramolecular amine salt of the DOPO derivative with a ring-opened structure was obtained by reinvestigation
