The toxicokinetics and distribution of 2-hydroxyethyl methacrylate in mice

Biomaterials, 2009
The cytotoxicity of dental composites has been attributed to the release of residual monomers from polymerized resin-based composites due to the degradation processes or the incomplete polymerisation of materials. 2-Hydroxyethyl methacrylate (HEMA) is one of the major components released from dental resin-based composites.

Copolymerisation of 2-hydroxyethyl methacrylate with siloxanyl monomers

European Polymer Journal, 1984
Abstract Acryloxymethylpentamethyldisiloxane (AMS) and methacryloxymethylpentamethyldisiloxane (MMS) have been prepared and purified chromatographically. Some physicochemical properties have been measured for these monomers as well as for highly purified 2-hydroxyethyl methacrylate (HEMA). Hydroxyl group analysis on copolymers of AMS with HEMA and of

Immobilization of Enzymes on 2‐Hydroxyethyl Methacrylate and Glycidyl Methacrylate Copolymer Brushes

Chemistry – An Asian Journal, 2014
AbstractThe 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.

Synthesis and Characterization of 2-Hydroxyethyl Methacrylate (HEMA) and Methyl Methacrylate (MMA) Copolymer Used as Biomaterial

Journal of Macromolecular Science - Pure and Applied Chemistry, 2010
A series of poly(methyl methacrylate-co-hydroxyethyl methacrylate) (PMMA-co-PHEMA), copolymers were synthesized by an emulsion polymerization technique. Copolymer compositions were determined by FT-IR and 1H-NMR spectroscopy.

Miscibility of poly(N-vinyl-2-pyrrolidone) with (methyl methacrylate)/(2-hydroxyethyl methacrylate) and (n-butyl methacrylate)/(2-hydroxyethyl methacrylate) copolymers

European Polymer Journal, 1991
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 ...

Water diffusion in methacrylate based copolymer hydrogels of 2‐hydroxyethyl methacrylate

Macromolecular Symposia, 2004
AbstractThe diffusion of water into cylinders of polyHEMA and copolymers of HEMA with THFMA, BMA and CHMA were studied over a range of copolymer compositions. The diffusion of water into the polymers was found to follow a Fickian, or case I mechanism.

Thermal degradation of copolymers of 2-hydroxyethyl methacrylate and alkyl methacrylates

European Polymer Journal, 1982
Abstract Thermal degradation of homopolymers of ethyl methacrylate (I), n-butyl methacrylate (II), 2-hydroxyethyl methacrylate (III), and copolymers of III with I and II were carried out by thermal volatilization analysis (TVA) up to 440°C with subsequent subambient thermal volatilization analysis (SATVA).

Thermal behaviour of 2‐hydroxyethyl methacrylate ‐ methyl methacrylate‐ copolymers

Die Angewandte Makromolekulare Chemie, 1980
AbstractCopolymerization 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.

Dual‐functional electrospun poly(2‐hydroxyethyl methacrylate)

Journal of Biomedical Materials Research Part A, 2011
AbstractPoly(2‐hydroxyethyl methacrylate) (pHEMA) has been widely used in many biomedical applications due to its well‐known biocompatibility. For tissue engineering applications, porous scaffolds that mimic fibrous structures of natural extracellular matrix and possess high surface‐area‐to‐volume ratios are highly desirable.

Preparation of Poly(2-hydroxyethyl methacrylate)-Collagen Composites

Journal of Biomaterials Applications, 1993
Linear 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.
