An amino-siloxane composition is presented. The amino-siloxane composition includes structure (I): wherein R' is independently at each occurrence a C1-05 aliphatic radical; R2 is a C3-C4 aliphatic radical; R3 is a C1-05 aliphatic radical or R4, wherein R4 comprises structure (II): and X is an electron donating group. Methods of reducing an amount of carbon dioxide in a process stream using the amino-siloxane composition are also presented. Une composition daminosiloxane est décrite. La composition daminosiloxane comprend la structure (I) où R' représente indépendamment à chaque occurrence un radical aliphatique en C1 à C5; R2 est un radical aliphatique en C3 à C4; R3 est un radical aliphatique en C1 à C5 ou R4, où R4 comprend la structure (II) et X est un groupe donneur délectrons. Il est également décrit des méthodes de réduction de la quantité de dioxyde de carbone dans un courant de traitement employant les compositions daminosiloxane.
