Synthesis of PEG-PPS-based polymer-biomolecule conjugates. The PPS block is formed by anionic ring-opening polymerization of an episulfide monomer, and endcapped with methyl acrylate. Conversion of the terminal methyl ester group to a carboxylic acid is accomplished under highly basic conditions to enable subsequent coupling of a PEG block and then a biofunctional ligand (e.g., peptides, amine-functionalized ssDNA) in modular fashion, yielding PEG-PPS-based polymer-biomolecule conjugates.
