Abstract

The invention concerns novel polyamines having formula (I) obtained from the reaction between a polyol diglycidylether and piperazine: in which n is a whole number between 0 and 30, R1 has different forms, R2 has formula (g5), and R2 has formula (g6) when n=0 The invention also concerns their preparation method and their use in an absorbing solution based on amines in order to selectively eliminate H2S from a gaseous effluent containing H2S and CO2.
