Peroxodisuiphate/Peroxodiphosphate-Ascorbic Acid Redox Initiated Graft Copolymerization of Acrylonitrile/Methylmethacrylate onto Polyethyleneterephthalate — A Close Comparison

Abstract

The kinetics of graft copolymerization of Poly acrylonitrile (PAN)/Poly methylmetha-crylate (PMMA) onto synthetic backbones such as nylon 6/nylon 66/Poly ethylene terephthalate (PET) initiated by peroxodisulphate (PDS)/Peroxodiphosphate (PDP)-Ascorbic acid (H₂A) redox systems were studied separately. Simultaneous homopoly-merizations were also followed under all conditions. A close comparison of the various rate parameters was made through analysis of results.

Key Words:

• Graft copolymerizations
• synthetic backbones
• peroxo salts-H₂A-Redox systems
• kinetic parameters
