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 کاملGraft Polymerization of Acrylonitrile onto Wheat Straw
Acrylonitrile was graft polymerized onto ground, water-washed wheat straw using Fe2 +-H 20 2 as initiator. Reaction conditions were selected to minimize homopolymer formation and ma.xi.mize the amount of polyacrylonitrile (PAN) grafted to straw. Polymerizations typically yielded straw-g-PAN containing 30-35% PAN. A two-step fractionation scheme was developed for determining the relative amounts...
متن کاملGraft Polymerization of Acrylonitrile onto Starch-Coated Polyethylene Film Surfaces
Starch-coated polyethylene (PE) films were prepared by immersing PE in a hot, jet cooked solution of starch. They were allowed to react with acrylonitrile (AN) in the presence of ceric ammonium nitrate initiator, and the graft polymerization that occurred produced starch-g-polyacrylonitrile (PAN) coatings that contained about 25 wt % grafted PAN. The starch-g-PAN coatings tightly adhered to the...
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...
