ABSTRACT:
The invention relates to a method of producing imide bond-containing compounds and flame retardants comprising such compounds. The method comprises reacting an acid anhydride with an isocyanate compound in an inert solvent in the presence of a tertiary amine as catalyst. The imide bond-containing compounds thus obtained provide flammable substances with good flame resistance and at the same time themselves have good heat resistance and weather resistance. Therefore, the flame retardants comprising such compounds have a wide field of application.
