Correction:

After publication of this work [1], we found an error in the figure legend for Figure two In Figure twoA, GPC chromatograms of the synthesized co-polymers were shown, but the

completed cPEG-PPS product contains some residual PPS-COOH, not H2N-PEG-COOH as originally described in the figure legend
