In a process for the preparation of aromatic polyamine mixtures which contain compounds of the general formula (I), H 2 NA-CH 2 -B-NH 2 in which A and B are 1,4-phenylene radicals, each of which can independently have 1 to 4 substituents selected from C 1-20 alkyl radicals and halogen atoms, are a compound of general formula (IV), HA-NH-CH 2 -HN-BH and / or a compound of the general formula (V) HA-NH-CH 2 -B-NH 2 where A and B are substituted as above, at a temperature in the range of 20 ° C to 200 ° C in the presence of a clay or layered silicate catalyst. |
