　　A series of new functional amino acids were prepared in high yield via thiol-ene Michael addition between L-cysteine and monomethoxy oligo(ethylene glycol)(OEG)functionalized methacrylates(OEGxMA)and acrylate(OEGxA).Subsequent ring opening polymerization(ROP)of these NCA monomers gave a series of OEGylated poly-L-cysteine(poly-EGxMA-C or poly-EGxA-C)homopolypeptides.Depending on the length of OEG side chains,poly-EGxMA-C and poly-EGxA-C polypeptides displayed different solubility and secondary structure in water.More importantly,the obtained polypeptides can display reversible thermo-responsive properties in water when the x value is between 3 and 5.
