Perfluoroelastomers
Perfluoroelastomers, curable by peroxidic route, obtainable by polymerizing the following monomers: a) tetrafluoroethylene (TFE); b) fluorovinylethers of general formula: CFX=CXOCF2OR c) bis-olefins having general formula: R 1R 2 C=CR 3-Z-CR 4=CR 5R 6 d) optionally, one or more fluorinated olefinic...

Summary: | Perfluoroelastomers, curable by peroxidic route, obtainable by polymerizing the following monomers: a) tetrafluoroethylene (TFE); b) fluorovinylethers of general formula: CFX=CXOCF2OR c) bis-olefins having general formula: R 1R 2 C=CR 3-Z-CR 4=CR 5R 6 d) optionally, one or more fluorinated olefinic comonomers selected from C2-C8 perfluoroolefins, perfluoroalkylvinylethers (PAVE) CF2=CFOR f, perfluoro-oxyalkylvinylethers CF2=CFOX, said perfluoroelastomers comprising iodine and/or bromine atoms in the chain and/or in end position, said halogen atoms deriving from "cure site" comonomers and/or from chain transfer agents used in polymerization. |
