New aminoalkyl anilines having the formula: STR1 wherein k is 0 or 1; QNH2 is a residue of formula STR2 which is situated in one of the positions of the benzene ring ortho or para to the amino group and wherein n is an integer from 1 to 15, R1 is C1 -C8 alkyl, R2 is C1 -C4 alkyl or R1 and R2, together with the carbon atom to which they are attached, form a C5 -C8 cycloalkylene residue, R3 is H or C1 -C6 alkyl, C3 -C8 cycloalkyl, or C6 -C10 aryl; and R4 and R5 are H or C1 -C4 alkyl; as well as the corresponding salts of compounds of formula I with organic or inorganic acids and metal salt complexes; process for their production; and their use as intermediates for polyamides.

New compounds having the formula: wherein p is 1 or 2 and the residues QNH2 are the same or different and each is a residue of formula: STR1 wherein n is an integer from 1 to 15; R1 is C1 -C8 alkyl; R2 is C1 -C4 alkyl; or R1 and R2 ; together with the carbon atom to which they are attached, from a C5 -C8 cycloalkylene residue; R3 is H or C1 -C6 alkyl, C3 -C8 cycloalkyl or C6 -C10 aryl; and Y is a divalent residue of formula: STR2 wherein R4 and R5 are H or C1 -C4 alkyl or, when p is 1, the group R4, together with the group X, can form a tetramethylene chain substituted by the group QNH2, X is NH2 or QNH2 or X may be combined with R4 as hereinbefore defined; and, when p is 2, X is a direct bond or a --CH2 -- or --O-- residue; as well as salts with organic or inorganic acids; and stereoisomers of formula I; and are useful as intermediates for other compounds e.g. polyamides.
