Dialkyl n substituted phosphoramidate containing flame retardants
Abstract
Abstract CELLULOSIC MATERIAL CAN BE FLAMEPROOFED BY INCORPORATING IN IT A FLAMEPROOFING AMOUNT OF A PHOSPHORUS COMPOUND HAVING THE FORMULA R1-O-P(=O)(-O-R2)-N(-R4)-CH2-O-R3 WHEREIN R1 IS A C1 TO C3 ALKYL GROUP, R2 IS A C1 TO C3 ALKYL GROUP, OR R1+R2 IS A C3 TO C5 ALKYLENE GROUP WITH ITS VALENCIES IN 1,3-RELATION; R3 IS H OR A C1 TO C3 ALKYL GROUP; AND R4 IS H, -CH3, -C2H5 OR -CH2OR3. NOVEL FLAMEPROOFING COMPOUNDS ARE THOSE IN WHICH EACH OF R1 AND R2 IS CH3, R4 IS H AND R3 IS H OR A C1 TO C3 ALKYL GROUP. OTHER NOVEL FLAMEPROOFING COMPOUNDS ARE THOSE IN WHICH R1 IS A C1 TO C3 ALKYL GROUP, R2 IS A C1 TO C3 ALKYL GROUP, R3 IS H OR A C1 TO C3 ALKYL GROUP AND R4 IS CH2OR3, IN WHICH R3 IS DEFINED AS ABOVE. WATER-SOLUBLE AMINOPLAST RESIN PRECONDENSATES CONTAINING AT LEAST TWO MOLES OF CONDENSED FORMALDEHYDE CAN BE COMBINED WITH THE PHOSPHORUS COMPOUNDS TO IMPROVE DURABILITY OF FLAMEPROOFING TO LAUNDERING.
