A method for preparing a polymer including the step of reacting carbon monoxide and a reactant pair having respective general formulas
a reactant having the general formula
in the presence of catalyst and free iodo or bromo ions. X is a nonortho halide selected from -Br and -I. n is an integer from 0 to 4. R¹ is selected from the group consisting of alkyl, arylalkyl, aryl, heteroaryl, and cycloalkyl. R² is selected from the group consisting of -O-, -S-, -
Each R⁵ is independently selected from the group consisting of alkyl and aryl, m is an integer from 1-12, and j is an integer between 0 and 300. R³ is selected from the group consisting of substituted aryl, unsubstituted aryl, substituted heteroaryl, and unsubstituted heteroaryl.
