Abstract

Compounds of the formula EQU P!(ACH.sub.2 NH.sub.2).sub.x in which P denotes a partially hydrogenated 1,3-diene oligomer residue, x is practically equal to 2 and A denotes a divalent residue such as ##STR1## are obtained by selective hydrogenation of compounds of formula P.sub.1 !(ACN)x in which P.sub.1 denotes a 1,3-diene oligomer residue.
