PHOSPHOBROMINATED POLYETHER POLYOLS, PROCESS FOR THEIR PREPARATION AND USE OF THESE POLYETHER POLYOLS IN THE PREPARATION OF FLAME-RESISTANT FLEXIBLE POLYURETHANE FOAMS |
摘要 |
Phosphobrominated polyetherpolyols which contain in their molecule oxyalkylene radicals bound to phosphorus atoms in the phosphate or phosphonate state and 1,4-dioxy-2,3-dibromo-2-butylene radicals in which the ratio of the total number of oxyalkylene radicals to the total number of phosphorus atoms is equal to at least 7. These polyetherpolyols can be used as flame-retarding reactive additives in the manufacture of flame-retardant flexible polyurethane foams involving polyetherpolyols, the foams possessing good comfort-conferring properties. |
