Post polymerization modification in flow

A polymer, comprising:

• a polycarbonate molecular backbone covalently bonded to a target functional group via a pendent functional group in accordance with chemical structure:
• wherein R1 is a first alkyl group,
• wherein R2 is selected from a first group consisting of an alcohol group, a second alkyl group, a benylic alcohol, an allylic alcohol, and a propargylic alcohol,
• wherein L is a linkage group comprising an alkyl chain and one or more end groups bonded to the alkyl chain, the one or more end groups selected from a second group consisting of an oxygen atom and a nitrogen atom,
• wherein R3 is the target functional group and selected from a third group consisting of a third alkyl group, an aromatic group, a heteroaromatic group, a pendent ether group, a thioether group, a alkyl halide group, a phosphonate group, an epoxide groups, a sulfonate group, a urea group, a thiourea group, a guanidinium group, a carbamate group, an ester group, and a carbonate group,
• wherein m is an integer greater than or equal to 2 and less than or equal to 1000,
• wherein A1 is the pendent functional group and comprises an aryl group,
• wherein the aryl group has a structure selected from the group consisting of:
• wherein X is a halide atom,
• wherein Y is an atom selected from a fourth group consisting of an oxygen atom, a nitrogen atom, and a sulfur atom, and
• wherein n is an integer greater than or equal to 2 and less than or equal to 8.
