Plasma induced graft polymerization of acrylic acid onto poly(ethylene terephthalate) monofilament
The graft polymerization of acrylic acid has been carried out on poly(ethylene terephthalate) (PET) monofilament to introduce carboxylic acid groups. The filament is treated with oxygen plasma for the introduction of peroxides and subsequently grafted with acrylic acid. The influence of monomer concentration, plasma exposure time and reaction temperature on the degree of grafting has been inves...
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, ...
متن کاملKinetic Study of Graft Polymerization of Acrylic Acid and Ethyl Methacrylate onto Starch by Ceric Ammonium Nitrate
Graft polymerization of acrylic acid (AA) and ethyl methacrylate (EMA) onto starch (St) were carried out in aqueous solution using ceric ammonium nitrate (CAN) as redox system under N2 atmosphere. The effect of pH, reaction time, temperature, concentrations of CAN, St, and monomers on the graft yield was investigated. Monomer reactivity was in the following order: AA>EMA.<em...
متن کاملRadiation graft post-polymerization of sodium styrene sulfonate onto polyethylene
Post-irradiation grafting of sodium styrene sulfonate (SSS) in the presence of acrylic acid (AA) has been investigated on polyethylene (PE) pre-exposed to gamma radiation at room temperature in the air. Special attention was paid to the effect of low molecular weight salt additives on the kinetics of graft copolymerization of SSS and AA. The presence of SSS links in the grafted PE copolymers wa...
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...
