Abstract: A process for devulcanizing fluoroelastomers having a fluorine content between 62% and 74% by weight vulcanized by ionic systems, preferably selected from bisphenol A and bisphenol AF, i.e. 2,2-bis(4-hydroxyphenyl)hexafluoropropane, the process including a step of heating the vulcanized fluoroelastomers in the presence of a hydrolysis composition having one or more chemical selected from water, water soluble alcohols, water soluble glycols and mixtures thereof, at a temperature from 350° C. to 430° C. Fluoroelastomers obtainable by this process and their use for the preparation of compounds and vulcanized compositions are also described.
