Organic polymeric compositions containing nitrilo methylol-phosphorus polymers and bromine compounds

Claim 1

IN A PROCESS OF REDUCING THE FLAMMABILITY OF AN ORGANIC TEXTILE BY IMPREGNATING THE TEXTILE WITH A NITRILO METHYLOL-PHOSPHORUS POLYMER PRODUCED BY REACTION AT LEAST ONE COMPOUND OF THE GROUP CONSISTING OF (HOCH2)4PCI, (HOCH2)3PO AND THE DERIVATIVES OF EITHER OF THEM CONTAINING A PLURALITY OF RESIDUAL PCH2OH GROUPS OF THE PARENT COMPOUND WITH AT LEAST ONE ORGANIC NITROGEN COMPOUND HAVING A MOLECULAR WEIGHT OF LESS THAN ABOUT 400 AND CONTAINING AT LEST ONE TRIVALENT NITROGEN ATOM AND AT LEAST TWO MEMBERS OF THE GROUP CONSISTING OF H AND CH2OH ATTACHED TO TRIVALENT NITROGEN ATOMS, THE IMPROVEMENT WHICH COMPRISES MIXING WITH THE NITRILO METHYLOL-PHOSPHORUS POLYMER IMPREGNANT A COMPOUND CONTAINING AT LEAST ABOUT 10% OF BROMINE IN THE FORM OF BROMINE ATOMS ATTACHED TO CARBON ATOMS, SAID COMPOUND BEING SELECTED FROM THE GROUP CONSISTING OF A POLYBROMOALCOHOL ESTER OF PHOSPHONITRILIC CHLORIDE, AN ADDITION PRODUCT OF A TERMINALLY UNSATURATED ALKENOL ESTER OF A PHOSPHONITRILIC CHLORIDE AND POLYBROMO C1-2 HYDROCARBON CONTAINING AT LEST TWO BROMINE ATOMS ATTACHED TO THE SAME CARBON ATOM, AN ADDITION PRODUCT OF AN N-ALKENYLATED MELAMINE AND A POLYBROMO C1-2 HYDROCARBON CONTAINING AT LEAST TWO BROMINE ATOMS ATTACHED TO THE SAME CARBON ATOM, AN ADDITION PRODUCT OF AB ALIPHATIC ACRYLAMIDE AND A POLYBROMO C1-2 HYDROCARBON CONTAINING AT LEAST TWO BROMINE ATOMS ATTACHED TO THE SAME CARBON ATOM, AND AN ADDITIONAL PRODUCT OF A TRIALKENYL PHOSPHATE AND A POLYBROMO C1-2 HYDROCARBON CONTAINING AT LEAST TWO BROMINE ATOMS ATTACHED TO THE SAME CARBON ATOM, TO PROVIDE IN THE TEXITILE A MIXTED IMPREGNANT IN WHICH PHOSPHORUS IN SAID NITRILO METHYLOL-PHOSPHORUS POLYMER IS CONTAINED IN STRUCTURES OF THE GROUP CONSISTING OF (-CH2)4PCI AND (-CH2)3PO IN AMOUNTS TO AT LEAST 0.5% OF THE TOTAL WEIGHT OF THE MIXTURE, AND IN WHICH FROM ABOUT 1 TO 20 PARTS OF NITROGEN CONTAINED IN NITRILO GROUPS AND FROM ABOUT 0.5 TO 20 PARTS OF BROMINE CONTAINED IN THE FORM OF BROMINE ATOMS ATTACHED TO CARBON ATOMS ARE PRESENT PER 1 PART OF PHOSPHORUS CONTAINED IN SAID STRUCTURE.
