Radio-iodide uptake by modified poly (glycidyl methacrylate) as anion exchange resin

Abstract

<jats:title>Abstract</jats:title><jats:p>Poly(glycidyl methacrylate) (PGMA) microspheres were prepared by radiation induced polymerization of glycidyl methacrylate (GMA) monomer. The factors affecting the degree of polymerization and yield (%) of PGMA such as type of solvent, monomer concentration, and irradiation dose were investigated. It was found that the PGMA yield (%) increases with increasing monomer concentration up to 50% and absorbed dose of 5 kGy. The resulting PGMA containing the epoxy group waschemically modified by hydroxyl amine to act as anion-exchange resin for uptake of</jats:p>

Radiation synthesis of Fe3O4/SiO2/glycidyl methacrylate/acrylonitrile nanocomposite for adsorption of basic violet 7 dye: Kinetic, isotherm, and thermodynamic study

“…Ring‐opening of a reactive epoxy group produces new functional groups which act as the chelate formation and ion exchange. [ 31 ] Additionally, several polymers including polyacrylonitrile showed attractive characteristics, for example, high thermal stability, high ionic conductivity, and desirable morphology for electrolyte uptake.…”

Assembly of CuO nanorods onto poly(glycidylmethacrylate)@polyaniline core–shell microspheres: Photocatalytic degradation of paracetamol

“…According to the literature, the thermal degradation of GMA‐based copolymers was suggested to start with the cleavage of poly‐GMA oxirane into fragments around 220°, and the second step might be associated with the ester bond breakdown in polymer (around 300°C), and the third step could be attributed to the total degradation of reminded polymer fragments (around 420°C). [ 40,41 ] Also, pure polyaniline has two major stages of weight loss. The first weight loss is due to loss of water at around 120°C, and massive weight loss starts from 310°C due to the thermo‐oxidative decomposition of polyaniline and may involve the degradation products such as N ‐phenylaniline, methane, acetylene, and carbazole.…”

Physico‐mechanical properties and flammability of PUR/PIR foams containing expandable graphite core‐shell composite particles

“…Signals at 2,996–2,950 cm −1 represent asymmetric CH stretching vibrations in the CH 2 groups present in the aliphatic chains and CH 3 of the EG_PGMA . The significant peaks at 1,680 and 1,182 cm −1 correspond to the CO and COC stretching vibration from the ester group . The weaker peak at 1,385 cm −1 is due to CH 2 and CH 3 bending .…”
