Some investigations on radiation-grafting of acrylic acid onto poly(tetrafluoroethylene-ethylene) copolymer films and its complex with copper salt solution

A study was made of the graft copolymers obtained by radiation-induced grafting of acrylic acid onto poly(tetrafluoroethylene-ethylene) (ET) films. The conversion of the graft copolymers (60 wt%) into metal acrylate copolymer complexes was carried out by treatment with various concentrations of aqueous CuCl2. These graft copolymer-metal complexes were studied by TR, UV spectrometry, X-ray diffraction (XDR), and electron spin resonance (ESR). The effect of temperature on the trunk, untreated grafted and treated grafted copolymer films was investigated by IR and thermogravimetric (TG) analysis. The influence of metal complexes of Cu2+ ions on the thermal properties and electrical conductivity was determined. It is assumed that such materials may be of great interest in the held of semiconducting materials, in addition to their resistance to degradation under high temperature, up to 300 degrees C.
