Beschreibung
Zusammenfassung:	Flame-resistant flexible polyurethane foam with high ageing stability contains a mixture of (A) hydroxyalkyl phosphonates and (B) chlorinated phosphate esters. An Independent claim is also included for a method for the production of this foam by reacting organic polyisocyanates with compounds containing at least 2 isocyanate-reactive hydrogen atoms, plus the usual blowing agents, stabilisers, activators etc., in presence of components (A) (halogen-free) and (B). Die Erfindung betrifft flammwidrige Polyurethanweichschäume mit hoher Alterungsbeständigkeit, dadurch gekennzeichnet, dass sie eine Mischung aus Hydroxyalkylphosphonaten und chlorierten Phosphorsäureestern enthalten sowie ein Verfahren zur Herstellung solcher flammwidriger Polyurethanweichschäume.
