摘要:
The present invention relates to a flame-retarding agent comprising a phosphoramidate compound represented by Formula (I): wherein R1 and R2 are each independently C1-3 alkyl, R11 and R12 are each independently C1-3 alkylene, R13 is C1-6 alkylene, B1 is hydrogen or C1-6 alkyl, and A is hydrogen or an organic group represented by Formula (Ia): wherein R3 and R4 are each independently C1-3 alkyl, R14 and R15 are each independently C1-3 alkylene, and B2 is hydrogen or C1-6 alkyl, wherein when B1 is C1-6 alkyl, and A is hydrogen, B1 and R13-A, taken together with nitrogen to which they are attached, may form a non-aromatic nitrogen-containing heterocycle, and wherein when B1 is C1-6 alkyl, A is an organic group represented by Formula (Ia), and B2 is C1-6 alkyl, B1 and B2, taken together with nitrogen to which they are attached and with R13, may form a non-aromatic nitrogen-containing heterocycle.

摘要:
Dicarbamic acid diesters of the formula ##STR1## in which R represents C.sub.1 - C.sub.4 -alkylene which is optionally substituted by one or more halogen atoms, and R.sub.1 and R.sub.2 independently of one another represent C.sub.1 - C.sub.4 -alkyl which is optionally substituted by halogen atoms or together with the oxygen atoms and the phosphorus atom form a 5-membered to 7-membered heterocyclic structure, R.sub.3 is hydrogen, hydroxymethyl or C.sub.1 - C.sub.4 -alkoxymethyl and R.sub.4 represents a divalent radical, with at least 2 carbon atoms, which is free from hydroxyl groups, and of which the two bonds must start from different carbon atoms, and wherein the phosphorus content of the diester is more than 5 % by weight, are suitable as flameproofing agents for textile materials, paper and plastics.
摘要:
Adducts of cyclic urea derivatives and dialkyl phosphites, containing glycidyl groups, for example adducts of a diglycidyl compound of hydantoins, substituted in the 5-position by alkyl groups or an alkylene group, and of diethyl phosphite or dimethyl phosphite. These adducts are used for the manufacture of flame-retarding plastics.
WHEREIN R IS SELECTED FROM THE GROUP CONSISTING OF PHENYL, LOWER ALKENYL AND HALOGEN SUBSTITUTED AND UNSUBSTITUTED LOWER ALKYL OF 1-6 CARBON ATOMS, X IS SELECTED FROM THE GROUP CONSISTING OF CHLORINE, BROMINE AND LOWER ALKYL OF 1-6 CARBON ATOMS, M IS AN INTEGER FROM 1-4 AND N IS AN INTEGER FROM 0-5, PROVIDED THAT THE SUM OF M AND N IS NOT GREATER THAN 6 AND WHEN M IS 1, X IS GREATER THAN O. THE COMPOUNDS OF THIS INVENTION ARE USEFUL AS FLAME RETARDANT AGENTS FOR TEXTILE MATERIALS AND IN THE PRODUCTION OF POLYMERS AND COPOLYMERS WHICH POSSESS FLAME RETARDANT PROPERTIES.
摘要:
A flame-retardant fabric may include a cellulosic fiber and a modacrylic fiber, the cellulosic fiber being a natural cellulose fiber containing a phosphorus compound, the modacrylic fiber containing an antimony compound, the flame-retardant fabric including the modacrylic fiber containing the antimony compound in an amount of 14 to 54 wt %, antimony in an amount of not less than 1.7 wt %, and phosphorus in an amount of 0.3 to 1.5 wt % with respect to the total weight of the flame-retardant fabric, and the flame-retardant fabric having a weight per unit area of not less than 160 g/m2. The flame-retardant fabric can be produced by subjecting a fabric including a natural cellulose fiber and a modacrylic fiber containing an antimony compound to flame-retardant treatment with a phosphorus compound.
