The Effect of Solvent on the Synthesis of α, ω-Functionalized Poly(ethyleneglycol) Macroinitiator

Polyethylene glycol (PEG) is utilized in many domains such as chemical industries, membranetechnology, pharmacology, and tissue engineering. In this research, the synthesis of PEG-basedmacroinitiators (Br-PEG۱۰۰۰-Br and Br-PEG۴۰۰۰-Br) with two different molecular weights weresurveyed with the tetrahydrofuran (THF) and dichloromethane (DCM) solvents. Fourier-transforminfrared (FTIR) and proton nuclear magnetic resonance (۱H-NMR) spectroscopy were used to verifythe synthesized macroinitiator chemical structure. The end-group functionalization percentage of theproduced macroinitiators with DCM solvent was higher than the attained samples with THF.
