RADIATION-INDUCED GRAFT-POLYMERIZATION OF ACRYLIC-ACID ONTO FLUORINATED POLYMERS .2. GRAFT COPOLYMER METAL-COMPLEXES OBTAINED BY RADIATION GRAFTING ONTO POLY(TETRAFLUOROETHYLENE-ETHYLENE) COPOLYMER

A study has been made on the graft copolymers obtained by radiation-induced grafting of acrylic acid onto poly(tetrafluoroethylene-ethylene) (ET) films. The conversion of the graft copolymer into metal acrylate copolymer complex was carried out by treatment with different metal salts. Such a prepared graft copolymer-metal complex was confirmed by different methods: IR, UV spectrometry, degree of coloration, and x-ray fluorescence. Some selected properties of the graft copolymer-metal complexes such as electrical conductivity, swelling behavior, and mechanical properties were investigated. The influence of metal complexes in the graft copolymers was determined and compared with the grafted films. The possibility of the practical uses for such prepared graft copolymer-metal complexes was discussed and determined. It was assumed that such materials may be of great interest in the field of semiconducting materials in addition to their applicability as cation-exchange membranes.
