Cation Exchange Membranes by Radiation-Induced Graft Copolymerization of Styrene onto PFA Copolymer Films. III. Thermal Stability of the Membranes
Thermal stability of cation exchange, PFA-g-polystyrene sulfonic acid membranes prepared by radiation-induced graft copolymerization of styrene onto PFA films followed by sulfonation was studied by thermal gravimetric analysis (TGA) and oven heat treatment. The tested samples included original and grafted PFA films as reference materials. All the membranes showed multistep decomposition pattern...
متن کاملInvestigations on Vinylene Carbonate. IV. Radiation Induced Graft Copolymerization of Vinylene Carbonate and N-Vinyl-N-Methylacetamide onto Polyethylene Films
Graft copolymerization of binary mixtures of vinylene carbonate (VCA) and N-vinyl-Nmethylacetamide (VIMA) onto low density polyethylene (LDPE) films was studied by the mutual y-irradiation technique. Sufficient amounts of functionally active VCA groups could be grafted onto the surface and the hydrophilicity of the surface was also improved. The grafting of VCA onto polyethylene films in the bi...
متن کاملRadiation-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 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 کاملPlasma-Induced Graft Polymerization of Acrylic Acid onto Poly(ethylene terephthalate) Films: Hydrophilic Modification
A complete and permanent hydrophilic modification of poly (ethyleneterephthalate) (PET) films is achieved by argon-plasma irradiation, subsequently grafting acrylic acid (AA) in vapor phase onto their surface. Both Ar plasma irradiation alone and post grafting AA rendered a complete hydrophilicity to PET surfaces. However, the hydrophilicity of the PET surface, only treated with the Ar plasma, ...
