Poly(ε-caprolactone-block-ethylene glycol methyl ether) [poly(RCL-b-mEG)] block copolymers were synthesized by "click" chemistry of polyethylene glycol methyl ether propargyl (mPEG-propargyl) and poly(ε-caprolactone) azido (RPCL-N3). Thus, mPEG-propargyl was acquired through the reaction of polyethylene glycol methyl ether with propargyl bromine. 2-[2-(2-Azidoethoxy)ethoxy]ethanol (N3ol) was synthesized by using 2-[2-(2-chloroethoxy)ethoxy]ethanol and sodium azide. Synthesis of RPCL-N3 was acquired using ROP of ε-caprolactone and N3ol. By using mPEG-propargyl and RPCL-N3, poly(RCL-b-mEG) block copolymers were obtained via "click" chemistry. The monofunctional homopolymers in the study were utilized for the syntheses of poly(RCL-b-mEG) block copolymers. The outputs were identified by scanning electron microscopy, 1H-nuclear magnetic resonance spectroscopy, differential scanning calorimetry, thermogravimetric analysis, Fourier-transform infrared spectroscopy, gel permeation chromatography, and dynamic light scattering instruments. The spectroscopic and thermal analysis of the block copolymers monitor that the copolymers were built through combination of ROP and "click" chemistry.
