Beschreibung
Zusammenfassung:Mixtures of (A) hydroxyalkyl phosphonates and (B) chlorinated phosphate esters. An Independent claim is also included for a method for the production of flame-resistant flexible polyurethane 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 Mischungen aus Hydroxyalkylphosphonaten und chlorierten Phosphorsäureestern, ein Verfahren zu ihrer Herstellung und ihre Verwendung.
