In Situ Cross-Linking of Polyanionic Polymers to Sustain the Drug Release from Theophylline Tablets
The aim of this study was to develop an extended-release tablet formulation using a new in situ cross-linking method. The effects of polyvalent cations on theophylline release from tablets made with the polyanionic polymers sodium alginate and sodium carboxymethylcellulose, were investigated. Different miliequivalents of the di and tri-valent cation, Ca2+ and Al3+, were added to tablet form...

متن کاملProperties of Polymers after Radiation Cross-linking
Radiation processing involves the use of natural or manmade sources of high energy radiation on an industrial scale. The principle of radiation processing is the ability of high energy radiation to produce reactive cations, anions and free radicals in materials. The industrial applications of the radiation processing of plastics and composites include polymerization, cross-linking, degradation ...
متن کاملChemical cross linking versus high energy electron beam cross linking of HDPE: electrical properties study
Cross linking of high density polyethylene (HDPE) was first performed via high energy10 Mev electron beam (EB) irradiation. HDPE was also cross linked withDicumyle peroxide (DCP).The gel content of samples was determined by solvent extraction.Degree of cross linking was evaluated by hot set apparatus; as well .In order to clarify the effectof nature of cross linking, correlation of electrical p...
متن کاملUltra-sonication-assisted solvent extraction of quercetin glycosides from 'Idared' apple peels.
Quercetin and quercetin glycosides are physiologically active flavonol molecules that have been attributed numerous health benefits. Recovery of such molecules from plant matrices depends on a variety of factors including polarity of the extraction solvent. Among the solvents of a wide range of dielectric constants, methanol recovered the most quercetin and its glycosides from dehydrated 'Idare...
