Vinylepoxide-amine acid gas adsorption-desorption polymers and oligomers, processes for preparing same, and uses thereof

摘要

An adsorption-desorption material, in particular, crosslinked vinylepoxide-amine polymeric materials having an M_w from about 500 to about 1×10⁶, a total pore volume from about 0.2 cc/g to about 2.0 cc/g, and an adsorption capacity of at least about 0.2 millimoles adsorbed CO₂ per gram of adsorption-desorption material, and linear vinylepoxide-amine polymeric materials having an M_w from about 140 to about 1×10⁶, a total pore volume from about 0.2 cc/g to about 2.0 cc/g, and an adsorption capacity of at least about 0.2 millimoles adsorbed CO₂ per gram of adsorption-desorption material. This disclosure also relates to processes for preparing the crosslinked and linear vinylepoxide-amine materials, as well as to selective removal of CO₂ and/or other acid gases from a gaseous stream using the vinylepoxide materials.
