Abstract: A novel hydroxy-capped comb-like block polymer, poly[poly(ethylene glycol)](HCPEG), was prepared via atom transfer radical polymerization(ATRP) of α-methylacryloyl-ω-hydroxyl-poly(ethylene glycol). The polymerization kinetics of the PHPEGMA was studied by gel permeation chromatography and 1H NMR. The semilogarithmic plot of monomer conversion vs. reaction time increases linearly before the conversion is up to more than 70% and the number-average molecular weights(Mn) by GPC increased linearly with increase of the monomer conversion up to 100%, while the polydispersity index remained fairly narrow with Mw/Mn<1.2.

Key words: Atom transfer radical polymerization(ATRP), α-Methylacryloyl-ω-hydroxyl-poly(ethylene glycol), Comb-like polymer
