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 ...

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 ...

Transport through crosslinked poly(2‐hydroxyethyl methacrylate) hydrogel membranes
Journal of Biomedical Materials Research, 1973AbstractThe transport of urea and other biologically interesting solutes in aqueous solution across poly(2‐hydroxyethyl methacrylate) (p‐HEMA) hydrogel membranes has been studied. The results show that p‐HEMA membranes have a high permeability to urea due to a strong interaction between the polymer and urea, and, in addition, they are consistent with a

2-Hydroxyethyl methacrylate-terminated polyurethane/polyurethane interpenetrating polymer networks
Journal of Biomedical Materials Research, 1997The interpenetrating polymer networks (INPs) of polyurethane (PU) and 2-hydroxyethyl methacrylate (MEHA)-terminated polyurethane (HPU) were prepared by solution polymerization. PU prepolymer was synthesized from 4,4-diphenyl methane diisocyanate (MDI) and poly(propylene oxide) glycol (PPG).

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 ...
