Abstract
1487937 Flame-proofed regenerated cellulose SANDOZ Ltd 7 Nov 1974 [9 Nov 1973 12 Feb 1974 10 June 1974 25 June 1974] 48291/74 Heading C3F [Also in Division C2] Regenerated cellulose contains, as a flameproofing agent, a compound of the Formula I where both Y's are oxygen or sulphur, both R 1 's are cyclohexyl, unsubstituted phenyl or phenyl substituted with up to 3 substituents selected from 1 to 3 chlorine atoms, a bromine atom in the para-position, 1 to 3 C 1-4 alkyl radicals and 1 to 3 C 1-4 alkoxy radicals, the aggregate of the carbon atoms in the alkyl and/or alkoxy radicals being 4 at most, and, when Y is sulphur, both R 1 's may also be methyl and both R 2 's are a radical of the formula wherein R 3 is hydrogen or C 1 -C 4 alkyl, and R 4 is C 1-12 alkyl, cyclohexyl, unsubstituted phenyl or phenyl substituted with up to 3 substituents selected from 1 to 3 chlorine atoms, a bromine atom in the para-position, 1 to 3 C 1-4 alkyl radicals and 1 to 3 C 1-4 alkoxy radicals, the aggregate of the carbon atoms in the alkyl and/ or alkoxy radicals being at most 4, or R 3 and R 4 together with the common nitrogen atom, and optionally with a further hetero-atom, form a saturated 5- or 6-membered heterocyclic ring, with the proviso that, when simultaneously Y is oxygen, R 3 is hydrogen and R 1 is substituted or unsubstituted phenyl, R 4 may only be unsubstituted or substituted phenyl. Optionally the cellulose may contain as an additional flame-proofing agent the reaction product of a glycol with phosphorus nitrile chloride.
