TRIAZOLIDINE-3,5-DIONE SALTS AND THEIR USE IN THE MODIFICATION OR FIRE-RESISTANT FINISHING OF POLYMERS

1. Triazolidine-3,5-dione salts according to the general formula I see diagramm : EP0044423,P9,F3 wherein R**1 and R**2 are identical or different and represent hydrogen, an aliphatic C1 -C10 , cycloaliphatic C4 -C10 , araliphatic C7 -C17 or aromatic C6 -C10 radical optionally substituted with halogen, hydroxyl, C1 -C10 alkoxy or C2 -C10 alkoxycarbonyl ; R**3 represents an m-valent aliphatic C1 -C20 , cycloaliphatic C4 -C15 , araliphatic C7 -C17 , or aromatic C6 -C15 radical, or a C2 -C12 cycloalkyl or aryl radical containing N, O and S, which radicals are optionally substituted with halogen, cyano, nitro, hydroxyl, amino, C1 -C10 alkyl- or dialkylamino, C1 -C10 alkoxy or C2 -C10 alkoxycarbonyl, it being possible for the radicals R**1 and/or R**3 also to be linked to one another as members of a cyclic C2 -C10 alkylene radical optionally also containing N, O or S in the ring, R**4 and R**5 are identical or different and represent hydrogen, an aliphatic C1 -C20 , araliphatic C7 -C17 or aromatic C6 -C15 radical optionally substituted with halogen, cyano, hydroxyl, C1 -C10 alkoxy and C2 -C10 alkoxycarbonyl or a C2 -C20 alkylcarbonyl radical optionally substituted with halogen and m represents an integer from 1 to 5.
