Abstract
Procedure for the production of regenerated cellulose of low flammability, characterized in that the cellulose is regenerated from a "cellulosic" medium containing a compound of formula I, where Y means oxygen or sulfur, or R1 and R2 each independently mean ** (See formula) ** wherein either R4 signifies hydrogen or (C1-C4) alkyl, and R5 signifies (C1-C12) alkyl, cyclohexyl, benzyl, phenyl or phenyl substituted by one to three substituents which are selected from 1 bromine atom, 1 to 3 chlorine atoms, one to three (C1-C4) alkyl groups and/or one to three (C1-C4) alkoxy groups, said substituents having a maximum of 4 carbon atoms in total, or R4 together with R5 and with the nitrogen atom to which they are linked, form a saturated 5- or 6-membered heterocycle containing 1 or 2 heteroatoms, or R1 and R2 together, form a group ** (See formula) ** where each Z, independently of each other, means hydrogen or (C1-C3) alkyl, and R3 means a group ** (See formula) ** where R4 and R5 are as defined above, or a group ** (See formula) ** where R1, R2 and Y are as defined above, and R6 means either a group -NH-R7-NH- where R7 means (C2-C10) alkylene or phenylene, ** (See formula) ** with the requirement that a) if R1 and R2 together form the group ** (See formula) ** the Y stands for sulfur, b) if any R4 signifies (C1-C12) alkyl, the Y signifies sulfur, and c) if any R4 means alkyl (C3 or C4), R5 of the same amino group means alkyl.
