Hydrophilic Natural Polymers for Sustained-controlled Release of Calcium Hydroxide
Calcium Hydroxide (CH) is commonly employed as intracanal medicament in endodontics. In order to maximize its therapeutic effects, it is essential to develop new approaches for preparing the controlled drug release systems which, in turn, facilities the dissociation of CH into calcium and hydroxyl ions. This work studies the sustained-controlled release of calcium ions and the effect of pH chan...

متن کاملChemical modification of maleic anhydride polymers with carbazole
Maleic anhydride (MAN) copolymers with methyl methacrylate(MMA), ethyl methacrylate(EMA), methyl acrylate(MA), ethyl acrylate (EA) and buthyl acrylate (BA) ( in a 1:1 mole ratio) were synthesized by free radical polymerizations method under vacuum -azobis(isobutironitrile)(AIBN) as an initiator of reaction at 701C. The copolymer compositions were determined using related 1H NMR spectra techni...
متن کاملEffects of water adsorption in hydrophilic polymers
The origin of the adsorption-induced phenomena in hydrophilic polymers, such as cellulose, lies at the atomistic scale. We use molecular dynamic simulations to investigate the mechanisms by which the adsorbing polymers change their properties upon water adsorption. Despite of their limited spacial and temporal capabilities MD simulations are able to reproduce the hygroscopic swelling and moistu...
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...
