A series of macroporous crosslinked copolymers of 2-hydroxyethyl methacrylate (HEMA) with methacrylic acid (MA) was prepared in the presence of fractionated particles of sodium chloride. The hydrogels were characterized by the number of pores in unit volume, the pore size, the water content in pores and diffusion parameters.

Genotoxicity and cytotoxicity of 2-hydroxyethyl methacrylate
Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2010Resin-based methacrylate materials are widely used in restorative dentistry. They are viscous substances that are converted into solid material via polymerization. This process, however, may be incomplete, leading to the release of monomers into the oral cavity and the pulp, which can be reached through the dentin micro-channels.

Copolymerizations of 2-hydroxyethyl methacrylate with alkyl methacrylates
European Polymer Journal, 1979Abstract Copolymerizations of 2-hydroxyethyl methacrylate with ethyl methacrylate and n -butyl methacrylate were studied in bulk at temperatures between 60 and 80° using benzoyl peroxide as initiator. The monomer reactivity ratios were calculated using Joshi-Joshi, Fineman-Ross and intersection methods.

Abstract The miscibility of poly( N -vinyl-2-pyrrolidone) (PVP) with (methyl methacrylate)/(2-hydroxyethyl methacrylate) (MMA/HEMA) and (n-butyl methacrylate)/(2-hydroxyethyl methacrylate) (BMA/HEMA) copolymers was studied. While PVP is immiscible with poly(methyl methacrylate), it is miscible with a MMA/HEMA copolymer containing 1.9 mol% of HEMA ...

Thermal behaviour of 2‐hydroxyethyl methacrylate ‐ methyl methacrylate‐ copolymers
Die Angewandte Makromolekulare Chemie, 1980AbstractCopolymerization of 2‐hydroxyethyl methacrylate (HEMA) with methyl methacrylate (MMA) was carried out in bulk in nitrogen atmosphere at 70°C using 0.2% benzoyl peroxide as initiator. Fractionation of the copolymers was done by precipitation method. The fractions were characterized by viscosity, NMR, IR and elemental analysis.

Preparation of Poly(2-hydroxyethyl methacrylate)-Collagen Composites
Journal of Biomaterials Applications, 1993Linear and three-dimensional polymer composites were prepared on the basis of poly(2-hydroxyethyl methacrylate)-pHEMA-and collagen. Their biological properties were tested by in vitro as well as in vivo methods. The composite material (unlike pure pHEMA) supported myoblast adhesion as well as their fusion into multinuclear myotubes in vitro. The three-

Wettability of hydrogels I. Poly(2‐hydroxyethyl methacrylate)
Journal of Biomedical Materials Research, 1975AbstractThe wettability characteristics of the contact lens material, PHEMA, with respect to water have been determined by using the sessile drop, and the captive air bubble techniques of contact angle goniometry. It is concluded that on PHEMA gels water does not spread spontaneously.

Immobilization of Enzymes on 2‐Hydroxyethyl Methacrylate and Glycidyl Methacrylate Copolymer Brushes
Chemistry – An Asian Journal, 2014AbstractThe immobilization of enzymes is of paramount importance to maintain their activity and stability. In this study, surface‐initiated atom‐transfer radical polymerization was applied to prepare poly(2‐hydroxyethyl methacrylate)‐block‐poly(2‐hydroxyethyl methacrylate‐co‐glycidyl methacrylate) brushes on glass slides.

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 ...
