Abstract The influence of 2-hydroxyethyl methacrylate (HEMA) on the properties of HEMA-added dental glass ionomer (HAGI) should be determined systematically to develop a smart restorative material. The purposes of this study were to determine the influence of incrementally added HEMA in experimental HAGIs on the color, translucency, opalescence ...

Water transport in crosslinked 2‐hydroxyethyl methacrylate
Polymer Engineering & Science, 2000AbstractWater transport in crosslinked 2‐hydroxyethyl methacrylate (HEMA) was investigated. Crosslinked HEMA was irradiated by gamma ray in vacuum for this study. The sorption data of de‐ionized water transport in crosslinked HEMA subjected to various gamma ray dosages are in excellent agreement with Harmon's model which accounts for Case I, Case II ...

2‐Hydroxyethyl methacrylate inflammatory effects in human gingival fibroblasts
International Endodontic Journal, 2012AbstractAimTo investigate the inflammatory response in human gingival fibroblasts (HGFs) treated with a relatively low 2‐hydroxyethyl methacrylate (HEMA) concentration by studying reactive oxygen species (ROS) production, cyclooxygenase‐2 (COX‐2) and tumour necrosis factor‐alpha (TNF‐α) gene expression, and prostaglandin E2 (PGE2) release ...

Bioerodible hydrogels based on 2‐hydroxyethyl methacrylate: Synthesis and characterization
Journal of Applied Polymer Science, 2002AbstractBiocompatible polymers with specific shape and tailored hydrogel properties were obtained by polymerization of mixtures of 2‐hydroxyethyl methacrylate (HEMA) with 1–8 wt % ethylene glycol dimethacrylate (EGDMA) or tetra(ethylene glycol) diacrylate (TEGDA) as crosslinking agents, by using a redox initiator.

The unperturbed dimensions of poly(2‐hydroxyethyl methacrylate)
Die Makromolekulare Chemie, 1977AbstractValues of the unperturbed dimensions of poly(2‐hydroxyethyl methacrylate) have been determined in five non‐ideal solvents using viscometric data and a number of different theoretical treatments. Values of the steric factor σ, the characteristic ratio C∞ and the expansion factor α were also calculated.

Conformational analysis of poly(2‐hydroxyethyl methacrylate)
Journal of Polymer Science Part A: Polymer Chemistry, 1991AbstractThe poly(2‐hydroxyethyl methacrylate) (PHEMA) is a disubstituted vinyl chain in which the substituents CO2CH2CH2OH and CH3 differ in size and shape. In order to verify the various characteristics of the PHEMA chain, the conformational energy calculations for meso and racemic diads, which are the segments consisting of the stereoregular ...

Copolymerization of 2-hydroxyethyl methacrylate with alkyl acrylates
European Polymer Journal, 1976Abstract Copolymerization of 2-hydroxyethyl methacrylate (HEMA) with methylacrylate (MA), ethylacrylate (EA), n -butylacrylate (BA) and methylmethacrylate (MMA) were studied in bulk at 60° using benzoyl peroxide as initiator. The monomer reactivity ratios were determined using several methods and are briefly discussed.

Abstract The molecular mobility of poly(2-hydroxyethyl acrylate) (PHEA) and of its copolymers with 2-hydroxyethyl methacrylate (H EM A) was determined by means of dynamic mechanical measurements with a torsional pendulum. The low-temperature dispersion assigned to the motion of the hydroxyethyl groups of the side chains was observed at -133°C (1 Hz ...
