In this study, a selective and specific sorbent for radium extraction was developed the first time using ion-imprinted polymer technology. A novel original approach used in order to screen best synthesis conditions. After identifying monomer candidates, porogen, complexation from electrospray ionization mass spectrometry experiments, solubility tests, conductimetry five polymers (IIPs) were syn...

N,N-dichloropolystyrene sulfonamide as a decontaminant was synthesized in 5 steps from styrene monomer. Styrene was first polymerized. Then, sulfonation reaction was performed by H2SO4 (c) followed by chlorination with POCl3 obtain chlorosulfonated polystyrene. Amidification reaction was then applied to get sulfonamide resin. Sulfonamide resin was treat...

Ethyl benzene used increasingly each year is the raw material of producing styrene monomer. This substanceis produced from benzene alkylation with ethylene or ethanol, depending on the availability and cost of rawmaterials. In this study benzene alkylation in the presence of ethanol in a catalytic fixed bed reactor inthree states of isotherm, adiabatic and non-isotherm-non-adiabatic is mathemat...

mechanical properties of wood/plastic composites manufactured by polyethylene and polypropylene blends (pp/hdpe) were studied. the sebs (styrene-ethylene butylene-styrene) and epdm (ethylene-propylene diene monomer) were used as compatibilizers to improve the compatibility and miscibility of the interface between hdpe and pp phases. the sawdust and polymers were compounded using an internal mix...

This study aims toward the application of composite phase-change material (CPCM) in electric vehicles, which suffers from leakage, high rigidity, and low thermal conductivity. In this study, a novel flexible with conductivity leakage has been proposed, presented, utilized battery module. Among these, polyethylene glycol (PEG), as component, styrene–butadiene–styrene (SBS) support material, ethy...

polymer nanocomposites containing metals have been used in a wide range of applications due to their versatility, and tunable characteristics including physical, chemical, biological and mechanical properties. in this research work polystyrene-silver nanocomposite has been produced using polymerization of a w/o microemulsion system. styrene monomer was used as the oil or continues phase of the ...

styrene polymerization through frp and atrp methods was carried out at 110oc, while in-depth studies were performed by monte carlo simulation.the changes in monomer conversion, initiator concentration, average molecular weight, and polydispersity index were computed over the course of the polymerization. as the results indicate, compared to atrp, the frp reaches higher conversion in a similar r...
