Abstract:
A peroxide curable fluoroelastomer having iodine atoms in a terminal position, and monomeric units in the chain deriving from an iodinated olefin of formula:CHR&boxH;CHâ€”Zâ€”CH2CHRâ€”Iâ€ƒâ€ƒ(I) wherein:R is â€”H or â€”CH3; Z is a C1-C18 (per)fluoroalkylene radical, linear or branched, optionally containing one or mote ether oxygen atoms, or a (per)fluoropolyoxyalkylene radical, said fluoroelastomer obtainable by a copolymerization process of the monomers in an aqueous micro emulsion of perfluoropolyoxyalkylenes or of fluoropolyoxyalkylenes having hydrogenated end groups and/or hydrogenated repetitive units, in the presence of a radical initiator and an iodinated chain transfer agent.
