“…The crystalline structure of CMC originates from strong interand intramolecular hydrogen bonds between the CMC chains. 22 However, these two bands became very marked and broad in the CMC-g-P(SPMA) hydrogel, indicating its amorphous glassy structure. These variations suggest that graft copolymerization destroys the intermolecular hydrogen bonds between oxygen containing functional groups in the CMC chains.…”

“…21 However, the CMC-g-P(SPMA) hydrogel shows new characteristic peaks at 1086 and 626 cm −1 , which are attributed to the stretching vibrations of S=O and S-O, respectively. 22 Moreover, an additional new band at 1718 cm -1 for the CMC-g-P (SPMA) hydrogel was assigned to the carbonyl (C=O) groups in the P(SPMA) chains. The increased intensity of the absorption peak at 3469 cm -1 may refer to the water bonded to the sulfonic groups.…”

A novel hydrogel was synthesized by grafting of poly(3-sulfopropyl methacrylate) (PSPMA) onto carboxymethyl cellulose (CMC) via the free radical polymerization technique, using N,N´-methylene bisacrylamide (MBA) as crosslinker and potassium persulphate (KPS) as initiator. CMC-g-P(SPMA) hydrogel and glucose were used as stabilizing and reducing agents, respectively, for the preparation of silver nanoparticles loaded hydrogel by a facile and green technique. The synthesized CMC-g-P(SPMA)/Ag nanocomposite was characterized by FTIR, UV-Vis spectroscopy, XRD, TGA, TEM and SEM techniques. The formed silver nanoparticles exhibited spherical shape and were homogenously dispersed in the hydrogel. These particles had an average particle size of 18 nm, as calculated from TEM results. The antibacterial and antifungal performance of the CMC-g-P(SPMA)/Ag nanocomposite was investigated and the results recommended the nanocomposite as an efficient and eco-friendly antibacterial and antifungal material.

Functionalized PVA microspheres are commonly used as drug carriers in the fields of pharmacy and medicine. With this aim, we obtained and test novel PVA-PVAc-AMPS sulfonated microspheres by free radical suspension polymerization of vinyl acetate (VAc) and 2-acrylamido-2-methyl-1-propanesulfonic sodium salt acid (AMPS), followed by saponification. The microspheres exhibited a porous core-shell structure with excellent sphericity, a mean size of 171 µm, and elasticity modulus comparable with commercial particles currently used in medical applications. Methylene blue (MB) which has shown similar adherence properties as the cytostatic drug doxorubicin was used as a model drug to study the drug loading/release characteristics of the sulfonated microspheres prepared in this work. 20.7 mg g-1 MB per gram of microspheres was the maximum adsorption capacity in two hours using UV-Vis absorption spectroscopy. The experimental data on adsorption were well described by the pseudo-second order kinetic model. The in vitro release profile of loaded MB microspheres showed rapid desorption in the first hour followed by slower MB release, reaching 8.6% elution at four hours. The diffusion process was found to be dominant in the MB desorption from the PVA-PVAc-AMPS microspheres.

“…Interpenetrating polymer networks (IPN) are the alloys of two or more different polymers in which one polymer is formed in the presence of other . Many naturally occurring backbones like gum dammar, gum rosin, collagen , gum xanthan, cellulose , guar gum, gum acacia, gum carragenan , gum ghatti, and gum arabic , have been used by the researchers for the synthesis of hydrogels with ameliorated characteristics such as enhanced liquid uptake capacity and more mechanical strength. Hydrogels are mostly synthesized by free radical polymerization, solution polymerization, inverse suspension, emulsion polymerization or by radiation polymerization .…”

In the recent study, microwave induced novel interpenetrating polymeric network (IPN) hydrogel based on gum copal-collagen (GcA-coll) has been reported for the efficient removal of malachite green dye from the waste water. The IPN [(GcA-coll)-cl-poly (AAm-ip-AA)] was synthesized using potassium persulfate (KPS)-N,N 0 -methylene-bis-acrylamide (MBA) as initiator-crosslinker system, acrylamide (AAm) as primary monomer and acrylic acid (AA) as secondary monomer under microwave radiations. The Response Surface Methodology (RSM) design was used to optimize the percentage swelling of the candidate IPN hydrogel. RSM based Central Composite Design (CCD) was applied to the three most crucial synthesis parameters like initiator concentration, monomer concentration and crosslinker concentration so as to maximize the percentage swelling. The optimum conditions for the removal of 88% malachite green dye from waste water are pH $ 7, initial dye concentration 5 12 mg mL 21 , adsorbent dose 5 500 mg. Pseudo first order and Pseudosecond order models were applied to study the kinetics and the mechanism of adsorption was studied by intraparticle diffusion model. The equilibrium data was further evaluated by Langmuir and Freundlich isotherm models. The synthesized IPN was found to be a propitious candidate to be used as a green adsorbent for removing malachite green dye from waste water. POLYM. ENG. SCI., 00:000-000,
