“…N-vinyl-2-pyrrolidone (VP) is a water-soluble, nonionic monomer that can be used to prepare hydrogels 10 . VP-based materials have been of interest in, for example, biomedical applications 11,12 . In recent years, polyacrylic acid (PAA) and its copolymers have often been used as carriers in drug release systems, because of their multifunctional nature, unique properties and good biocompatibility 13,14 .…”

Hydrogels have been extensively explored for biomedical applications due to their ability to absorb high water content in its structure, which gives excellent biocompatibility. This work aims at obtaining biocompatible hydrogels with potential for use in increasing the mechanical strength of bone substitutes, or controlled drug release. Poly (N-vinyl-2-pyrrolidone) hydrogels were prepared by free radical polymerization with and without the addition of acrylic acid. Azobisisobutyronitrile and ammonium persulfate were used as initiator and N,N-methylenebisacrylamide was used as the crosslinking agent. The characterization of the hydrogels was performed by thermogravimetric analysis, differential scanning calorimetry, infrared spectroscopy and swelling properties. The results obtained demonstrate different degrees of crosslinking and swelling of up to 490 ± 30%. The different properties of the hydrogels suggest different applications.

“…The probabilities of the different links are therefore: [12] [13] [14] In this case obviously the majority of the links are C M -C M . The * refers to p CM-these calculations CV* = p CM-CV + p CV-CM and a 2 must be included in the equation.…”

“…Due to the mentioned compositional heterogeneity, an efficient crosslinking of all the chains (i.e. C M and C V ) is not an easy task, and actually the crosslinker homology may play a key role in the network structure and properties, as it has previously been addressed theoretically by Reinecke et al 13 and by Lai 14 . Thus, a crosslinker bearing a methacrylate or a VP-like functionality would crosslink preferentially C M or C V chains, respectively.…”

Self-Structuring in Amphiphilic Networks Prepared by Single Conventional Radical Copolymerization of n-Butyl Methacrylate and Vinylpyrrolidone

Amphiphilic networks segregated in hydrophilic and hydrophobic domains are very attractive materials because they show unique properties related to the combination of both components. In this work, these types of networks have been obtained in a very simple way by single standard bulk radical photocopolymerization of vinylpyrrolidone, and n-butylmethacrylate, in the presence of 1 mol % of crosslinkers with different homology towards both components. The crosslinker homology (methacrylate or VP-like functionalities) has shown to have a strong influence on the sol content and on the different properties of the materials, such as segregation or the variation of the storage modulus with temperature and hydration. The experimental results are in good agreement with a theoretical prediction of the network formation carried out assuming that the reaction may be described compositionally by the terminal model. The most efficient crosslinking has been obtained using an asymmetric crosslinker bearing simultaneously methacrylate and VP-like groups.3

“…This can be attributed to the high reactivity of MBA crosslinker toward acrylate monomers. [18] On the other hand, it was found that the crosslinked PAN have lower SF values than PAMPS and AN=AMPS copolymers. This can be attributed to the high reactivity of the PAN toward divinyl benzene DVB and acrylate crosslinker, which is much higher than methacrylate crosslinkers.…”

Crosslinked acrylonitrile/acrylamidoxime/2-acrylamido-2-methylpropane sulfonic acid (AN/ AAx/AMPS) based hydrogels was prepared by radical solution polymerization technique. The structures of hydrogels were characterized by FTIR analysis and the results were consistent with the expected structures. These hydrogels were used for the separation of Cd(II), Cu(II), and Fe(III) ions from their aqueous solutions. The influence of the uptake conditions such as pH, time, and initial feed concentration on the metal ion binding capacity of hydrogel was also tested. The selectivity of the hydrogel toward the different metal ions tested was Cd(II)>Fe(III)>Cu(II). The recovery of metal ions was also investigated in acid media.
