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 acr
ylate copolymer complexes was carried out by treatment with various co
ncentrations of aqueous CuCl2. These graft copolymer-metal complexes w
ere studied by TR, UV spectrometry, X-ray diffraction (XDR), and elect
ron spin resonance (ESR). The effect of temperature on the trunk, untr
eated grafted and treated grafted copolymer films was investigated by
IR and thermogravimetric (TG) analysis. The influence of metal complex
es of Cu2+ ions on the thermal properties and electrical conductivity
was determined. It is assumed that such materials may be of great inte
rest in the held of semiconducting materials, in addition to their res
istance to degradation under high temperature, up to 300 degrees C. (C
