Hydrogen-bond structures in poly(2-hydroxyethyl methacrylate) (PHEMA) were investigated by infrared (IR) spectroscopy and quantum chemical calculations (QCC). A monomer of 2-hydroxyethyl methacrylate (HEMA) and model compounds of methyl acetate (MA) and methanol (MeCH) were also used. Evidences for OH center dot center dot center dot O=C and OH center dot center dot center dot OH types of hydrogen-bonds were observed in an IR spectrum of a PHEMA solid. it was estimated from the present Study that 47.3% of OH groups on the PHEMA side chain terminal are engaged in the OH center dot center dot center dot O=C type of hydrogen-bond, while the rest contributes to the OH center dot center dot center dot OH type of hydrogen-bond.
