FIELD: chemistry.
SUBSTANCE: ethylene/tetrafluoroethylene copolymer has content of chlorine atoms of not more than 70 parts per million(ppm) and copolymerisation ratio (molar ratio) of polymerised structural units based on tetrafluoroethylene/polymerised structural units based on ethylene ranging from 40/60 to 70/30. Said copolymer contains polymerised structural units based on one more copolymerisable monomer as an optional component in amount of 0.1-10 mol %, in terms of all polymerisable structural units on the whole, and has volume flow rate ranging from 0.01 to 1000 mm3/s.
EFFECT: obtaining thermally stable ethylene/tetrafluoroethylene copolymer having low content of chlorine atoms.
