ABSTRACT:
A method for preparing a polymer including the step of reacting carbon monoxide and a reactant pair having respective general formulas ##STR1## a reactant having the general formula ##STR2## in the presence of catalyst and free iodo or bromo ions. X is --Br or --I. n is an integer from 0 to 4. R.sup.1 is selected from the group consisting of alkyl, arylalkyl, aryl, heteroaryl, and cycloalkyl. R.sup.2 is selected from the group consisting of ##STR3## wherein each R.sup.5 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.
