(Figure , S5 and S6). H NMR spectrum (DMSO-d6), the characteristic peaks at 1.0-1.2 (EbiB end chain and the CH3), The disappearance of vinyl peaks at 5.60-5.62, 6.09-6.12 and 6.26-6.32 ppm confirmed conversion of monomer to poly(AAla) after 30 min reaction time. Peak at 1.5-2.3 (CH2CH in the backbone, PAAla), 3.8-4.6 (NCHCOO), and 7.3-8.4 (NH) ppm are clearly seen, which are attributed to the poly(A-Ala-OH) main chain. Resonance of acidic and amidic protons at 12.68 and 7.6 ppm, C-Br end chain 4.27 ppm (Figure ) . Using PAAla40-Br as a macroinitiator in the presence of Zn/PMDETA as the catalyst/Ligand system amphiphilic block copolymer PAAla-b-PMMA was synthesized. The NMR of homopolymer and block copolymer showed that in block there are two central blocks were present one comes from PAAla part and other from the PMMA part. NMR peak and IR spectra. This block copolymer contains two part one is hydrophilic (PAAla) and other one hydrophobic (PMMA). Typically,
