In a process for the moulding agglomeration of fine solid particles with an added inert non-aqueous liquid phase with use of a binder, the thermal stability of the agglomerates needed to be increased. This was accomplished by using, as binder, polymers at least partially soluble in the liquid phase, and having a content of dicarboxylic anhydride groups, furthermore by processing the binder, liquid phase and the solid material to be agglomerated to a mouldable mass, and combining this, having been shaped, with anhydride-reactive polyamines in such a manner that the polyamines react with the anhydride groups at least on the surface of the moulded solids. |
