Abstract
A polymer compound containing groups having the chemical structure: where NHis a primary amine, and R is not hydrogen, and a polymer backbone wherein two of the R groups are part of the polymer backbone. A method of synthesizing a polymer includes polymerizing amine-convertible monomers to produce a polymer, causing a deprotection reaction with the polymer to form an isocyanate, decomposing the isocyanate to form a polymer containing primary amines. A method to separate COfrom other gases comprising using a sorbent containing a polymer compound having the structure: where NHis a primary amine, and R is not hydrogen, and a polymer backbone wherein two of the R groups are part of the polymer backbone.
