FIELD: chemistry.
SUBSTANCE: invention discloses a radiation-chemical method of producing luminescent fluoroplast-4. A block or film type article made from polytetrafluoroethylene undergo treatment with gamma-rays with average energy of 1.25 MeV at temperature higher than the melting point of the crystalline phase. Treatment is carried out in the presence of water vapour at pressure 10-2-1 mm Hg and dose rate of 1-5 Gy/s to an absorbed dose of 200 kGy.
EFFECT: disclosed method ensures obtaining a novel modification of fluoroplast-4 - polytetrafluoroethylene having intense fluorescence in the visible spectrum.
