METHOD OF PRODUCING FLUORINATED MONOMERS Russian patent published in 1999 - IPC

Abstract RU 2127719 C1

FIELD: polymers disposal. SUBSTANCE: pure fluorinated monomers are obtained with high yield by pyrolysis of fluorinated polymers, which is performed by feeding finely crumbled polymer with steam into fluidized-bed reactor. Material of fluidized bed is inert granulated material, whereas steam is used as fluidizing gas. Temperature of pyrolysis ranges from 500 to 900 C. For pyrolysis, tetrafluoroethylene is largely used. EFFECT: new polymer degradation technology developed. 3 cl, 1 dwg, 2 tbl
