METHOD OF PRODUCING STABILISED CHEMICAL-RESISTANT POLYHEXAFLUOROPROPYLENE OXIDES Russian patent published in 2009 - IPC C08G65/323 C08G65/00 C08G65/32 C08F214/28

Abstract RU 2371452 C1

FIELD: chemistry.

SUBSTANCE: production of polyhexafluoropropylene oxides with reactive fluroanhydride groups through treatment with elementary fluorine while heating. The process is carried out in a single step in a nickel vertical vessel, filled with a spring washer. Elementary fluorine is directly fed into the reaction mass while heating to 120 to 240°C.

EFFECT: design of an efficient method of producing chemical-resistant polyhexafluoroproylene oxides.
