The Journal of Hand Surgery, 2002
Polyhydroxyethyl methacrylate (pHEMA) membranes coated on one side with chondroitin sulfate (CS) were used to block adhesion physically and to reduce friction between healing flexor tendons and the surrounding tissue in rabbit forepaws after surgical repair.

A series of polymers system based on poly(butyl methacrylate) (PBMA) and poly (hydroxyethyl methacrylate) semi-interpenetrating polymer networks (semi-IPN) (PBMA/ PHEMA = 70/30 by weight) have been attained by a sequential polymerization method using divinylbenzene (DVB) as cross-linking agent.

Biomaterials, 1998
Naturally occurring, biocompatible, and biodegradable polyhydroxybutyrate-co-hydroxyvalerate (PHBV), and synthetic, non-degrading polyhydroxyethylmethacrylate (PHEMA) membranes were prepared and their mechanical properties were studied. Their performances were compared with the interpenetrating networks (IPN) prepared by photopolymerization of HEMA in ...

International Ophthalmology, 2017
Artificial cornea is the effective treatment option for corneal blindness. One of the challenges with the artificial cornea is limited, or no tissue integration necessitates reimplantation due to necrosis or corneal melting. We propose here a new formulation approach for core-skirt incorporating graphite in the outer skirt region to improve cell ...

Journal of Applied Polymer Science, 2020
AbstractPorous nanofibers were prepared from a combination of polyglycerol sebacate (PGS) and polyhydroxyethyl methacrylate (PHEMA) and loaded with tranexamic acid (TA) using the electrospinning method. The nanofibers were optimized for their morphology, diameter size, porosity, TA loading, release profile and mechanical behavior.

Neuroradiology, 2002
The purpose of the study was the evaluation of 2-polyhydroxyethyl methacrylate (2-P-HEMA) for endovascular liquid embolization of experimental side-wall aneurysms following stent protection in a canine model. The swelling behaviour and polymerization characteristics of 2-P-HEMA in different solutions were investigated in vitro.

Abstract A series of composite sorbents based on the rigid macroporous polyhydroxyethyl methacrylate (HEMA)-based support filled with soft dextran gel was prepared. The affinity dyes Cibacron Blue and Remazol Brilliant Blue were then immobilized on both the original HEMA and the composite (HEMA-D) sorbents. The properties of HEMA and HEMA-D sorbents,

Viscoelasticity of Calf Hide Impregnated with Radiation-Polymerized Polyhydroxyethyl Methacrylate
1986In order to combine the desirable properties of synthetic polymers (elasticity and water, chemical, and biological resistance) with those of animal hide (strength, flexibility, and dyability), composites can be formed between the two types of material. Actually, adding materials to hide has long been an aspect of traditional leathermaking, usuaslly to ...

Abstract Three classes of water may exist in certain hydrogels. We have previously labeled these as X water (bulk water), Z water (bound water) and Y water (intermediate forms we call interfacial water). Bulk gel conductivity data for poly (2-hydroxyethyl methacrylate) (PHEMA) were obtained.
