Background The present work objective was to prepare and to observe the effect of ethylene
glycol dimethacrylate on swelling and on drug release behavior of pH-sensitive acrylic acid …

Objective of the present work was to synthesize hydrogels of acrylic acid/polyvinyl alcohol
(AA/PVA) by free radical polymerization by using glutaradehyde (GA) as crosslinkers. The …

The objective of current study was to fabricate PEG based hydrogels cross linked with
monomer ie acrylic acid and 2, Acrylamide-2-methyl propane sulfonic acid (AMPS) in …

Oral drug administration is convenient with pH dependent drug delivery system since the
drug has to pass through different pH environments in gastro intestinal (GI) tract. The pH …

The hydrogels prepared by free radical copolymerization of acrylamide and itaconic acid
were investigated with regard to their composition and crosslinking degree to find materials …

Objective: Hydrogels are high-water content materials prepared from cross-linked polymers
that are able to provide sustained, local delivery of a variety of therapeutic agents. Use of the …

The purpose of present study is to load Metformin HCl into pH-sensitive hydrogels to have
sustained release over a period of time. The hydrogel was synthesized from naturally …

The development of pH sensitive, biocompatible and biodegradable hydrogels as novel
drug delivery systems was carried out to achieve localized drug delivery. Poly [N-vinyl …

The basic explorations of structure property correlations and the variety of commercial and
biological applications all attest to the fact that amphiphilic is highly useful. In this work, the …

In this study, pH responsive polymers composed of methacrylic acid, acrylamide, and N‐
hydroxyethyl acrylamide were synthesized by free radical polymerization technique. The …
