FLAMMSCHUTZMITTEL FUER KUNSTSTOFFE

3-Hydroxy-5-phosphono-1,2-oxaphospholanes can be synthesized from beta -dicarbonyl compounds by reaction with 2 moles of an diorganophosphite. The products are usable as flameproofing agents for plastics, particularly for polyurethanes and epoxide resins which are able to react with the hydroxyl gro...

Beschreibung
Zusammenfassung:	3-Hydroxy-5-phosphono-1,2-oxaphospholanes can be synthesized from beta -dicarbonyl compounds by reaction with 2 moles of an diorganophosphite. The products are usable as flameproofing agents for plastics, particularly for polyurethanes and epoxide resins which are able to react with the hydroxyl group of the oxaphospholanes.
