FIELD: chemistry.
SUBSTANCE: invention discloses fluorinated elastomer latex which contains an aqueous medium, a fluorinated elastomer dispersed in the aqueous medium in amount of 10-60 wt %, and a fluorinated emulsifying agent of formula (1): C2F5OCF2CF2OCF2COOA, where A is a hydrogen atom, an alkali metal or NH4 which has excellent dispersion stability. Disclosed is a fluorinated elastomer obtained through coagulation of fluorinated elastomer latex, which has low content of emulsifying agent, as well as a product moulded from fluororubber obtained by cross-linking the fluorinated elastomer and which has excellent physical properties.
EFFECT: improved environmental and sanitary-technical properties of the elastomer and improved properties of the fluororubber.
