Claims
- 1. Flameproofed regenerated cellulose containing, as a flameproofing agent, an effective amount of a compound of formula, ##STR57## wherein R.sub.3 " is straight or branched chain C.sub.3 -C.sub.5 alkylene; or a divalent radical selected from ##STR58## with the proviso that when R.sub.3 " is straight or branched chain C.sub.3 -C.sub.5 alkylene, it is other than alkyl-substituted methylene; and
- each of R.sub.4 " and R.sub.5 " is, independently, methyl; ethyl; --CH.sub.2 Cl; or --CH.sub.2 Br; with the provisos that: (a) when R.sub.4 " is --CH.sub.2 Br, R.sub.5 " is other than --CH.sub.2 Cl; and (b) when R.sub.5 " is CH.sub.2 Br, R.sub.4 " is other than --CH.sub.2 Cl.
- 2. Flameproofed regenerated cellulose according to claim 1 containing, as a flameproofing agent, the compound of the formula ##STR59##
- 3. Flameproofed regenerated cellulose according to claim 1 containing, as a flameproofing agent, the compound of the formula ##STR60##
- 4. Flameproofed regenerated cellulose according to claim 1 containing, as a flameproofing agent, the compound of the formula ##STR61##
- 5. A method for producing flameproofed regenerated cellulose comprising regenerating cellulose from a cellulose-containing medium containing a flameproofing effective amount of a flameproofing agent of the formula ##STR62## wherein R.sub.3 " is straight or branched chain C.sub.3 -C.sub.5 alkylene; or a divalent radical selected from ##STR63## with the proviso that when R.sub.3 " is straight or branched chain C.sub.3 -C.sub.5 alkylene, it is other than alkyl-substituted methylene; and
- each of R.sub.4 " and R.sub.5 " is, independently, methyl; ethyl; --CH.sub.2 Cl; or --CH.sub.2 Br; with the provisos that: (a) when R.sub.4 " is --CH.sub.2 Br, R.sub.5 " is other than --CH.sub.2 Cl; and (b) when R.sub.5 " is CH.sub.2 Br, R.sub.4 " is other than --CH.sub.2 Cl.
- 6. A method according to claim 5, wherein the amount of said flameproofing agent is from 8% to 25% of the weight of the cellulose in the cellulose-containing medium.
- 7. A method according to claim 5 wherein the cellulose-containing medium contains, in addition to the flameproofing agent, a reaction product of a phosphorus nitrile chloride with a glycol, a cyclodiphosphazane or a thionocyclodiphosphazane.
- 8. A method for producing flameproofed regenerated cellulose comprising applying to regenerated cellulose a solution or an aqueous dispersion containing a flameproofing effective amount of a flameproofing agent of the formula ##STR64## wherein R.sub.3 " is straight or branched chain C.sub.3 -C.sub.5 alkylene; or a divalent radical selected from ##STR65## with the proviso that when R.sub.3 " is straight or branched chain C.sub.3 -C.sub.5 alkylene, it is other than alkyl-substituted methylene; and
- each of R.sub.4 " and R.sub.5 " is, independently, methyl; ethyl; --CH.sub.2 Cl; or --CH.sub.2 Br; with the provisos that: (a) when R.sub.4 " is --CH.sub.2 Br, R.sub.5 " is other than --CH.sub.2 Cl; and (b) when R.sub.5 " is CH.sub.2 Br, R.sub.4 " is other than --CH.sub.2 Cl.
