Abstract

Preparation of halogenated imides derived from hydrazine and halogenated dicarboxylic acid anhydride and capable of being employed as flame-retardant agents for plastics. The condensation of hydrazine and of halogenated dicarboxylic acid anhydride is carried out in aqueous medium at a temperature ranging from 40 to 225 DEG C with an anhydride/hydrazine molar ratio lower than 2.
