Abstract
An amino-siloxane composition is presented. The amino-siloxane composition includes structure (I): wherein R1 is independently at each occurrence a C1-C5 aliphatic radical; R2 is a C3-C4 aliphatic radical; R3 is a C1-C5 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.
