Poly (hydroxyethyl methacrylate-glycidyl methacrylate) films modified with different functional groups: In vitro interactions with platelets and rat stem cells.
Copolymerization of 2-hydroxyethylmethacrylate (HEMA) with glycidylmethacrylate (GMA) in the presence of α-α'-azoisobisbutyronitrile (AIBN) resulted in the formation of hydrogel films carrying reactive epoxy groups. Thirteen kinds of different molecules with pendant NH2 group were used for modifications of the p(HEMA-GMA) films. The NH2 group served as anchor binding site for immobilization of ...
متن کاملHydrophilic molecularly imprinted poly(hydroxyethyl-methacrylate) polymers.
Highly cross-linked 2-hydroxyethyl methacrylate (HEMA) and poly(ethylene glycol) dimethacrylate with poly(ethylene glycol) of molecular weight 600 (PEG600DMA) were molecularly imprinted with hydrophilic templates glucose and proxyphylline using water as a solvent. Glucose-imprinted polymers showed increased recognitive capacity compared to nonimprinted polymers as well as increased glucose upta...
متن کاملBlends of polystyrene and poly(n-butyl methacrylate) mediated by perfluorocarbon end groups
Structurally well-defined C4F9, C7F15, C10F21 and C13F27 end-functionalized polystyrene (RF-PS) and polybutylmethacrylate (RF-PBMA) were prepared by Atom Transfer Radical Polymerization using RF–tagged initiators. Blends (1/1 wt/wt) of these polymers were studied by differential scanning calorimetry (DSC), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS), optical transmitta...

15 صفحه اول2,3-Dihydroxypropyl methacrylate and 2-hydroxyethyl methacrylate hydrogels: gel structure and transport properties
The drying kinetics were examined in four cross-linked polymers that form hydrogels: 2,3-Dihydroxypropyl methacrylate (DHPMA) and 2-hydroxyethyl methacrylate (HEMA) and two random copolymers, with one-to-one and three-to-one HEMA-to-DHPMA molar ratios. The hydrogels were saturated with buffered, isotonic saline solution and deionized water; weight loss kinetics were monitored at temperatures fr...
