Effect of HEMA on bonding to dentin
Dental Materials, 1992The present study investigated the effectiveness of treating dentin with 2-hydroxyethyl methacrylate (HEMA) prior to application of an adhesive resin. The adhesive resin was 5% 4-methacryloxyethyl trimellitate anhydride (4-META) in methyl methacrylate (MMA) combined with poly-MMA powder. Polymerization of this resin was initiated by tri-n-butyl borane (

HEMA reactivity with demineralized dentin
Journal of Dentistry, 20102-Hydroxyethylmethacrylate (HEMA) was compared to its epoxy analogue, glycidoxypropylmethacrylate (GMA), for reactivity with 2,6-diaminohexanoic acid (Lysine), an amino acid present in collagen possessing a reactive amino side chain. The aim was to verify whether HEMA could chemically react with collagen fibers.Capillary electrophoresis was used to ...

In order to obtain target/redox shell cross-linked micelles (TCM), copolymers poly(ε-caprolactone)-poly(2-hydroxyethyl methacrylate/methacrylate-alpha lipoic acid) and poly(ε-caprolactone)-poly(2-hydroxyethyl methacrylate/methacrylate-folate, PCL-P(HEMA/HEMA-LA) and PCL-P(HEMA/HEMA-FA) were designed and synthesized.

Influence of free chains on the swelling pressure of PEG-HEMA and dex-HEMA hydrogels
International Journal of Pharmaceutics, 2007Insight in the osmotic behavior of degrading hydrogels is of great importance in the design of biodegradable hydrogels for biomedical applications. This study compares the degradation behavior of PEG-HEMA (hydroxyethylmethacrylated polyethylene glycol) and dex-HEMA (hydroxyethylmethacrylated dextran) hydrogels.

From HEMA monomers to poly-HEMA systems simulations
2022There is plenty of experimental literature characterizing hydroxyethyl methacrylate (HEMA)-based physical and chemical hydrogels, due to their spread applications in numerous fields, especially in the biomedical one. Transport properties of poly-HEMA hydrogels as well as systems dynamics are of particular interest owing to delivery issues, whether in ...

Methods for Microencapsulation with HEMA-MMA
2003Encapsulation of cells in a membrane prior to implantation holds potential for controlling the adverse immune response that may be generated against the transplanted cells, by physically isolating the cells from the host's immune system. If successful, encapsulation eliminates or minimizes the adverse effects of immunosuppressive therapy and permits ...

Journal of Applied Polymer Science, 1992
AbstractThe copolymers of poly[HEMA‐co‐(PVA‐AA)] and poly[HEMA‐co‐(PVA‐MA)] were synthesized and characterized. The presence of PVA‐AA in the copolymer increased the mechanical strength but decreased the water content of the material. The presence of PVA‐MA, on the other hand, caused a decrease of mechanical strength and an increase of water content ...

Metabolism of TEGDMA and HEMA in human cells
Biomaterials, 2010Previous in vivo studies have shown that the comonomers triethylene glycol dimethacrylate (TEGDMA) and 2-hydroxyethyl methacrylate (HEMA) from dental materials can be metabolised to CO(2) by two postulated pathways: an epoxide and a valine pathway. In the epoxide pathway the formation of pyruvate is postulated and in valine pathway the formation of l ...

We report the preparation of stable micelles from random copolymers of 2-hydroxyethyl methacrylate (HEMA) and perfluorophenyl azide (PFPA)-derivatized HEMA (HEMA-PFPA). The copolymers were synthesized by RAFT polymerization at room temperature under mild conditions without affecting the azide functionality.
