TLDR
In this article, the synthesis regularities and the swelling behaviour of hydrogels have been studied and it was shown that increasing of PVP concentration in feed composition also as radiation dose accompanied of increase of yield of gel fraction and decrease of swelling degree.About:

Theoretical investigation of the effect of NP-10 concentration on the swelling behavior of AA-NaAA/NP hydrogel
TL;DR: In this article, a superabsorbent polymer (SAP), acrylic acid- sodium acrylate/polyoxyethylene (10) nonyl phenyl ether (AA-NaAA/NP), was synthesized with ammonium persulfate as the initiator and N,N′-methylene bisacrylamide (MBA) as the crosslinker.

Designing and In Vitro Characterization of pH-Sensitive Aspartic Acid-Graft-Poly(Acrylic Acid) Hydrogels as Controlled Drug Carriers
TL;DR: In this paper , aspartic acid-graft-poly(acrylic acid) hydrogels were used for the controlled release of acetaminophen. But, the authors did not consider the use of acrylic acid as an active ingredient.

Synthesis and Evaluation of Alginate-Based Nanogels as Sustained Drug Carriers for Caffeine
TL;DR: In this article , a polymeric network of nanogels for sustained release of caffeine was designed by a free-radical polymerization technique for the sustained delivery of caffeine, and the results showed that a high gel fraction was seen with the increasing feed ratio of polymer, monomer, and crosslinker.

Application of chitosan-based polysaccharide biomaterials in cartilage tissue engineering : a review
TL;DR: Some biomaterials, which have been suggested to promote chondrogenesis and to have potentials for tissue engineering of articular cartilage, are reviewed and a new biomaterial, a chitosan-based polysaccharide hydrogel, is introduced and discussed in terms of the biocompatibility with chondrocytes.

Oral drug absorption enhancement by chitosan and its derivatives.
TL;DR: Mono-carboxymethylated chitosan (MCC) is a polyampholytic polymer, able to form visco-elastic gels in aqueous environments or with anionic macromolecules at neutral pH values, and appears to be less potent compared to the quaternized derivative.
