✦ Synopsis

A study was made of the graft copolymers obtained by radiationinduced grafting of acrylic acid onto poly(tetraÑuoroethyleneÈethylene) (ET) Ðlms. The conversion of the graft copolymers (60 wt%) into metal acrylate copolymer complexes was carried out by treatment with various concentrations of aqueous These graft copolymerÈmetal complexes were studied by IR, CuCl 2 . UV spectrometry, X-ray di †raction (XDR), and electron spin resonance (ESR). The e †ect of temperature on the trunk, untreated grafted and treated grafted copolymer Ðlms was investigated by IR and thermogravimetric (TG) analysis. The inÑuence 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 Ðeld of semiconducting materials, in addition to their resistance to degradation under high temperature, up to 300¡C. Society

## Abstract Grafted copolymer of poly(tetrafluoroethylene ethylene) (ET) with acrylic acid (AAc) was prepared by direct radiation method. The obtained films were modified by treating with small amounts of Co^2+^ and K^+^ ions (1.0 wt %). The effects of such treatment on the thermal stability and el
