Radiation-Induced Graft Copolymerization of Acrylonitrile onto Kappa-Carrageenan
The monomer, acrylonitrile, was graft copolymerized onto kappa-carrageenan (kC) using γ-rays as initiator. The reactions were carried out in a homogenous aqueous medium. After removal of the homopolymer, the graft copolymer was characterized by FTIR spectroscopy. A plausible mechanism of grafting has also been suggested. The effect of various factors affecting on grafting, i.e. dose of δ-rays a...
متن کاملPreparation of polymer decorated graphene oxide by γ-ray induced graft polymerization.
Herein, we report a facile approach to decorate graphene oxide (GO) sheets with poly(vinyl acetate) (PVAc) by γ-ray irradiation-induced graft polymerization. The content of PVAc in the obtained sample, i.e., PVAc grafted GO (GO-g-PVAc) is calculated by the loss weight in thermogravimetric analysis (TGA) curves. A GO-g-PVAc sample with a degree of grafting (DG) of 28.5% was well dispersed in com...
متن کاملPolymethylmethacrylate/Silver Nanocomposite Prepared by γ-Ray
Polymethylmethacrylate-silver (PMMA/Ag) nanocomposite is synthesized by irradiating the solution of silver ions in methylmethacrylate monomer by γ-ray. In this method, polymerization of the methylmethacrylate monomer and the silver ion reduction occurred simultaneously. Optical properties of the PMMA/Ag solutions are investigated using UV-Vis spectroscopy. The structural characterizations of th...
متن کاملGamma Radiation-Induced Graft Copolymerization of Styrene onto Poly(ethyleneTerephthalate) Films
Gamma radiation-induced graft copolymerization of styrene onto poly(ethylene terephthalate) (PET) films was studied using simultaneous irradiation technique. The effects of grafting conditions on the degree of grafting were investigated. The grafting conditions include monomer concentration, irradiation dose, dose rate, and the type of solvent. Moreover, the effect of the addition of crosslinki...
متن کاملGamma Radiation Induced Graft Copolymerization of Typical Monomers onto Poly (3-hydroxybutyrate)
The preparation of several graft copolymers obtained by radiation induced graft copolymerization of typical monomers onto poly (3hydroxybutyrate) is reviewed. The general mechanisms by which graft copolymerization reaction proceed under various irradiation conditions are described. Main attention is given to the structure, properties, synthesis and characterization of the graft product, as well...
