POLYETHERPOLYOLS PHOSPHOBROMES, PROCESSES FOR THEIR OBTAINING AND USE OF THESE POLYETHERPOLYOLS IN THE MANUFACTURE OF FLAME RETARDANT POLYURETHANE SOFT FOAMS

摘要

POLYETHERPOLYOLS PHOSPHOBROMES COMPRISING OXYALKYLENE RADICALS IN THEIR MOLECULE ASSOCIATED WITH PHOSPHATE OR PHOSPHONATE PHOSPHORES ATOMES AND 1,4-DIOXY-2,3-DIBROMO-2-BUTENYLENIC RADICALS IN WHICH THE RATIO BETWEEN THE TOTAL NUMBER OF OXYALKYLENE RADICALS AND THE TOTAL NUMBER OF PHOSPHORUS ATOMS IS EQUAL TO AT LEAST 7. / P P THESE POLYETHERPOLYOLS ARE USED AS FLAME RETARDANT REAGENTS IN THE MANUFACTURE OF FLAME RETARDANT POLYURETHANE FOAMS FOR THE INTERVENTION OF POLYETHERPOLYOLS PRESENTING GOOD PROPERTIES OF COMFORT.
