Said first intermediate (I1) is reacted with a lactone and/or a hydroxy carbon acid in step b) in order to obtain a second intermediate (I2) followed by step c), wherein said second intermediate (I2) is reacted optionally with alkylene oxide in order to obtain a third intermediate (I3). Afterwards, said third intermediate (I3) is reacted in optional step d) with a second alkylene oxide (AO2) in order to obtain the novel alkoxylated polyamines.
