| 摘要 |
Reaction products containing at least two amidophosphate radicals are disclosed. They have been produced from (1) an amidophosphate of the formula <IMAGE> wherein R1 is lower alkyl or both R1's together are lower alkylene, (2) formaldehyde, (3) optionally an aliphatic diol with 2 to 6 carbon atoms, (4) optionally a lower alkanol. If a diol according to (3) has been used, R1 in the amidophosphate according to (1) can also be lower alkenyl or halogenoalkyl. The disclosed reaction products are suitable for flameproofing organic fibre materials, especially cellulosic textiles.
