The diblock copolymer of styrene and chloromethyl-4-vinyl-benzene was obtained by means of reverse addition fragmentation chain transfer reaction living free radical polymerization. The chloromethyl groups in PS-bPCVB were transformed into azidomethyl groups, and then into 1,2,3-triazol groups via click chemistry. The diblobk copolymer containing 1,2,3-triazol groups was thus obtained. The results from NMR spectra suggested a complete transformation from chloromethyl groups to triazol groups.
