New fluoroelastomers are described, comprising monomeric units deriving from a bis-olefin having general formula: [Figure] (I) wherein: R1, R2, R3, R4, R5, R6, equal or different from each other, are H or alkyls C1-C5; Z is an alkylene or cycloalkylene radical C1-C18, linear or branched, optionally
New fluoroelastomers are described, comprising monomeric units deriving from a bis-olefin having general formula: [Figure] (I) wherein: R1, R2, R3, R4, R5, R6, equal or different from each other, are H or alkyls C1-C5; Z is an alkylene or cycloalkylene radical C1-C18, linear or branched, optionally containing oxygen atoms, preferably at least partially fluorinated, or a (per)fluoropolyoxyalkylene radical. Such products are endowed with improved processability, especially during calendering of the vulcanization mixture, along with superior mechanical and workability properties during extrusion and injection molding, with a very good mold release.
