Original Paper


Synthesis of poly(epichlorohydrin-b-ethylene glycol) block copolymers was obtained via “click” chemistry of polyepichlorohydrin propargyl (PECH-propargyl) and polyethylene glycol azido (PEG-N3) with different molecular weights. For this purpose, polyethylene glycol bromine (PEG-Br) was obtained by reaction of PEGs with various molecular weights and 3-bromopropionyl chloride. PEG-N3 was synthesized by using PEG-Br with sodium azide (NaN3). PECH-propargyl was synthesized using polyepichlorohydrin and propargyl chloride. By reacting PECH-propargyl and PEG-N3, the block copolymers were obtained. The primary parameters, for example time, amount of solvent, and concentration, were evaluated. The products were characterized by FT-IR, 1H-NMR, GPC, TGA, SEM, and fractional precipitation techniques.
