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.

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.

International Journal of Polymeric Materials, 1975
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 ...

Copolymers of 2‐hydroxyethyl methacrylate and alkyl methacrylates. I. Synthesis and characterization
Journal of Polymer Science: Polymer Chemistry Edition, 1985AbstractCopolymerization of 2‐hydroxyethyl methacrylate (HEMA) with ethyl methacrylate (EMA) and n‐butyl methacrylate (BMA) was carried out in bulk at 70°C ± 1°C using 0.2% benzoyl peroxide as initiator in nitrogen atmosphere. Number average molecular weight (Mn) of the copolymers was determined by dynamic osmometry. Intrinsic viscosity [η] of HEMA‐BMA

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 ...

An ultrastructural study of the biocompatibility of poly(2‐hydroxyethyl methacrylate) in bone
Journal of Biomedical Materials Research, 1975AbstractBecause of the unique properties for swelling in a fluid medium and variable modulus of elasticity, hydrophilic methacrylates may be of potential usefulness for implanting prosthetic devices in bone. To investigate the biocompatibility, electron micrographic studies were done on specimens of poly(2‐hydroxyethyl methacrylate) imbedded in bone ...

Pressurized polymerization for reaction casting of poly(2‐hydroxyethyl methacrylate)
Journal of Biomedical Materials Research, 1981AbstractHomopolymers of the hydrogel poly(2‐hydroxyethyl methacrylate) are produced with no observable bubbles trapped in the lattice by performing the free radical initiated polymerization reaction under pressure (700 kPa). Implantable hydrogel structures of intricate and exact geometry, such as nipples for ureteral anastomoses in the prosthetic ...
