Synthesis and characterization of diethanolamine-containing glass ionomer cement

In this study, glycidyl methacrylate (GMA) diethanolamine was synthesized and incorporated into polyacid main chains, which would be used for glass ionomer cements (GICs). The polymer was prepared by the free radical polymerization of acrylic acid and itaconic acid with readily synthesized GMA diethanolamine. Effects of molecular weight, polymer content in the liquid composition, powder/liquid ratio, and aging on compressive strength and diametral tensile strength were investigated. Working and setting time, water sorption and solubility (Wsl), pH value of the immersed solution, and microhardness were also measured. The experimental GICs had comparable mechanical properties to Fuji II GICs while exhibiting less Wsl and high hydrophilicity. The results suggested that the experimental GICs held promise as biocompatible and workable cement for application. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
