| titleOfInvention | Process for the stabilization of fluoropolymers |
| abstract | Melt-processible copolymers of at least two halogenated comonomers from a defined class, especially perhalogenated comonomers, and particularly perfluorinated comonomers, of improved thermal stability are obtained by first contacting the copolymers with a stabilizing agent selected from bases (ammonia or amines) having a boiling point at normal pressure of at most 130 DEG C. and tertiary alcohols having up to 8 carbon atoms, to form an intermediate, drying the intermediate at about 70 DEG -150 DEG C., and fluorinating the intermediate at a temperature between 20 DEG C. and the lowest temperature at which the copolymer exhibits a solid state transition, then removing excess fluorine and by-products and recovering the stabilized copolymer. Such stabilized copolymers are useful for a variety of technically important applications, including as clading for optical fibers, substrates for electronic components, thermal laminates, pipes, tubes, and fittings, etc. |
