  • Method for stabilization of fluoro-organic copolymers of the ethylene series
    Patent number: 4128707
    Abstract: A method for stabilization of fluoro-organic copolymers of the ethylene series which comprises mixing said copolymer with xenon difluoride taken in an amount ranging from 0.1 to 15% by weight of the starting copolymer at a temperature not exceeding 20.degree. C.The method according to the present invention makes it possible to produce copolymers and articles therefrom having an increased thermal stability and longer service life as compared to those produced by the prior art methods. The method is versatile. It is applicable to any type of copolymer of the ethylene series containing bonds which are weaker than the C - F bond.
