TETRAFLUOROETHYLENE-HEXAFLUOROPROPYLENE-ETHYLENE COPOLYMERS, LAMINATED MATERIAL, AND FILM

摘要

FIELD: chemistry of polymers. SUBSTANCE: claimed invention describes copolymers comprising 45-55 mole % tetrafluoroethylene, 10-20 mole % hexafluoropropylene and 23-40 mole % ethylene units at melting temperature from about 140 to about 170 C and which can be treated from melt. They are useful as coatings for temperature- sensitive substrates. EFFECT: improved properties of the coatings.
