ABSTRACT:
The current invention relates to a fluorinated elastomer latex containing an aqueous medium, a fluorinated elastomer dispersed in the aqueous medium in an amount of from 10 to 60 mass % and a fluorinated emulsifier represented by the formula (1): C2F5O(CF2CF2O)mCF2COOA (wherein A is a hydrogen atom, an alkali metal or NH4, and m is an integer of from 1 to 3), which employs no perfluorooctanoate emulsifier and which is excellent in dispersion stability of the fluorinated elastomer.
