The dimethacrylate macromonomer named bis (2-hydroxy-3-(méthacryloyloxy) propyl) fumarate (HMPF) was synthesized by ring opening reaction of epoxide function glycidyl methacrylate (GMA) with maleic anhydride (MA) in presence Maghnite-H+ as a catalyst at room temperature and free solvent. is proton exchanged montmorillonite clay it an Algerian activated sulfuric acid 0,23M. HMPF characterized FT...

Polyacrylate and guanidine-based nanoparticles which involve acrylate monomers and glycidyl methacrylate modified oligo-guanidine were prepared by a seeded semi-continuous emulsion polymerization. The results from transmission electron microscope and dynamic light scattering measurements showed that the nanoparticles were spherical in shape and the particle size was in the range of 80–130 nm. A...

A novel magnetic polymer/bentonite composite was prepared by suspension copolymerization of glycidyl methacrylate and ethylene glycol dimethacrylate in the presence bentonite (MB-PGME) functionalized with diamine hexamethylene (MB-PGME-ED MB-PGME-HD). The obtained samples were characterized terms structure as well thermal, morphological properties. sorption rhenium (Re) tungsten (W) from aqueou...

An antithrombotic nanoconjugate was designed in which a designed biomimetic peptide LWWNSYY was immobilized to the surface of poly(glycidyl methacrylate) nanoparticles (PGMA NPs). Our previous work has demonstrated LWWNSYY to be an effective inhibitor of integrin α2β1-collagen interaction and subsequent thrombus formation, however its practical application suffered from the formation of cluster...

Thermoplastic sugar beet pulp (thermo-mechanical processing was discussed in previous studies) was formed into film strips by extrusion. Film tensile properties are discussed according to the molecular structure of external plasticizer. Sorbitol, fructose and adipic acid have a marked antiplasticizing effect, while urea and xylitol gave higher ultimate tensile stress than glycerol for a compara...

Hyaluronic acid (HA; also called hyaluronan) is a naturally derived, nonimmunogenic, nonadhesive glycosaminoglycan that has important roles in several wound-healing processes. In previous work, we created photocrosslinkable glycidyl methacrylate-HA (GMHA) hydrogel biomaterials that were cytocompatible, biologically active, and had a decreased rate of hyaluronidase degradation compared with nati...

A porous polymer monolithic column for solid-phase microextraction and chemiluminescence detection was integrated into a simple microfluidic chip for the extraction and determination of catechins in green tea. The porous polymer was prepared by poly(glycidyl methacrylate-co-ethylene dimethacrylate) and modified with ethylenediamine. Catechins can be concentrated in the porous polymer monolithic...

This study demonstrates the preparation, structure, and properties of polymer-impregnated wood (PIW) based on novel Muchelia macclurei wood through the in-situ polymerization of vinyl and functional monomers. Mixed monomers of glycidyl methacrylate (GMA) and ethylene glycol dimethacrylate (EGDMA) (2:1 molar ratio) were effectively vacuum/pressure impregnated into the cellular structure of the f...

Capillaries with inner diameters of 550 microm have successfully been packed with 1.5-microm octadecyl silica particles using frits made of macroporous polymers by the UV photopolymerization of a solution of glycidyl methacrylate and trimethylolpropane trimethacrylate. This type of frit is found superior to one made of low-melting point poly(styrene-co-divinylbenzene) beads. Bubble formation is...
