“…By incorporation of DMC into the network, hydrogels can be used for selective removal of dyes or metal ions. 28,29 Especially, the incorporation of quaternary ammonium groups imparts hydrogels response to a number of external stimuli such as salt and pH, and thus allows their application in drug release systems. 30,31 In the present work, we attempted to develop Salecan-g-PDMC hydrogels with different Salecan content for controlled release application.…”

“…They also possess excellent fluid retention properties under pressure2, 3 as they immobilize the fluid by entrapment rather than by holding it in the structure. Because of the aforementioned features, SAPs are finding extensive applications in drug delivery as carriers,4–6 agricultural and horticultural fields as soil conditioners,7–10 disposable diapers,11 hygienic napkins,12 cement,13 effluent treatments for removing heavy metals, and dye,14, 15 disposal of radioactive uranium ions,16 absorbing oil,17 coal dewatering,18 sensors19 etc. Besides, they are also employed in communication cables, humidity control, artificial snow for winter sports, toys, cosmetics and as an industrial absorbent, and for prevention of moisture ingress into walls and ceilings 20, 21.…”

A series of superabsorbent polymers (SAP) were synthesized by free radical thermal copolymerization of acrylic acid and N‐isopropyl acrylamide monomers using trimethylolpropane triacrylate as crosslinker. They were characterized by FT‐IR and thermal stability (TGA/DTG), and evaluated for their water and fertilizer uptake and release characteristics under different crosslinker levels, temperature, pressure, and pH. The observed maximum absorption of water by the SAP was 1130 g/g of polymer. The release was modeled which showed a non‐Fickian mechanism. The water uptake of SAP was correlated with the average molecular weight between the crosslinks and crosslink density. Analysis of the weight loss data from TG in air revealed a zero order kinetics for the initial degradation step with an activation energy (AE) of 70.8 kJ/mol. The AEs for water uptake and release for thermal degradation were also determined through Arrhenius plots. The results inferred that the synthesized SAP can be exploited for commercial agricultural applications. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

“…It is evident from the Figure 3 that the PMETAC superabsorbent exhibited an equilibrium swelling capacity ( S eq ) of 141.8 g of water/g of SAP. The equilibrium swelling capacity of the cationic SAP in this study was almost equal to the ethylene glycol dimethacrylate crosslinked [ N ‐vinyl pyrrolidone/2‐(methacryloyloxyethyl)trimethylammonium chloride] based hydrogels (78–155 g/g, depending on the composition and the crosslinker concentration),21 and much higher than that of the radiation synthesized MALETMC‐based copolymeric hydrogels (10 g/g) 22…”

A cationic monomer [2‐(methacryloyloxy)ethyl]trimethylammonium chloride was polymerized using N,N′‐methylenebisacrylamide as the crosslinker to obtain a cationic superabsorbent polymer (SAP). This SAP was characterized by Fourier transform‐infrared spectroscopy, and the equilibrium swelling capacity was determined by swelling in water. The SAP was subjected to cyclic swelling/deswelling in water and NaCl solution. The conductivity of the swelling medium was monitored during the swelling/deswelling and was related to the swelling/deswelling characteristics of the SAP. The adsorption of five anionic dyes of different classes on the SAP was carried out and was found to follow the first‐order kinetics. The Langmuir adsorption isotherms were found to fit the equilibrium adsorption data. The dye adsorption capacity of the SAP synthesized in this study was higher than that obtained for other hydrogels reported in the literature. © 2012 Wiley Periodicals, Inc. J. Appl. Polym.
