Mixture of bis(2-hydroxyalkyl) N,N-di(lower alkyl)aminomethanephosphonates with polyols |
摘要 |
Bis(2-hydroxyalkyl) N,N-di(lower-alkyl)aminomethyl-phosphonates are described. These phosphorus-containing polyols can be incorporated into polyurethane foams to render the latter fire retardant. They have the advantage over closely related phosphorus-containing polyols that they are autocatalytic in the polyurethane foam forming reaction and that they can be mixed with the polyol component of the polyurethane foam forming composition to give a mixture (premix) which can be maintained in storage for prolonged periods without showing any signs of deterioration.
