Abstract:
1. An acid gas adsorption-desorption material comprising a crosslinked polyvinyl-amine material having a weight average molecular weight of from about 500 to about 1×10 6 , a total pore volume of from about 0.2 cubic centimeters per gram (cc/g) to about 2.0 cc/g, and an adsorption capacity of at least about 0.2 millimoles of CO 2 adsorbed per gram of adsorption-desorption material, or mixtures thereof; wherein said crosslinked polyvinyl-amine material is produced by reacting one vinyl halide material comprised of at least one haloalkyl functional group and at least one vinyl functional group, with at least one organo-amine, said at least one organo-amine comprising a linear amine, a branched amine, a polyamine, or mixtures thereof, and further reacting with a chloromethyl-functionalized additive selected from the group consisting of poly(styrene-co-chloromethylstyrene), poly(methacrylate-co-chloromethylstyrene), and poly(styrene-co-4-methylstyrene-chloromethylstyrene, under conditions sufficient to produce crosslinked polyvinyl-amine material.
