Polyhydroxyethyl methacrylate-linked by-polysulfone amphiphilic polymer conetworks of two types of segments with Tg above room temperature are presented. The conetworks are prepared by free radical copolymerization of methacryloyl-terminated PSU macromers with 2-ethyl methacrylate, followed by removal of the TMS protecting groups by acidic hydrolysis ...

A kind of polyurethane rubber (PU)/n-octadecane (n-OD)@silicon dioxide (SiO2)-polymethyl acrylate (PHEMA) form-stable phase change material (PCM) was fabricated in this paper. n-OD@SiO2-PHEMA microcapsules were prepared in one-pot, through interfacial hydrolysis polycondensation of alkoxy silanes and radical polymerization of HEMA.

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.

In the experiments on rabbits histological specimens with embolus radiopaque by iodides, bromides of silver and by (3-amino-2,4,6-triiodobenzyl) oil acid have been investigated 7 days after implantation. Optimum emboli were used in clinical practice during preoperative procedure for endovascular occlusion of liver and kidney arteries.

Two types of polyethylene terephthalate (Dacron) substrates (USCI DeBakey Vasculour-D and USCI Sauvage filamentous) have been selectively coated with Poly-hydroxyethyl methacrylate (P-HEMA) in a two-stage process. Using scanning electon microscopy (SEM) techniques, the microstructural details of the fabrications were identified. The first stage of this

The study analyses the possibility of using polyhydroxyethyl methacrylate as a material for the slow release of antibiotic in periodontal pockets. The antibiotics examined were tetracycline and metronidazole. The aim of the study was to evaluate the biocompatibility of the material with periodontal tissue and the efficacy of the 2 prepared systems. Two
