CURABLE FLUOROELASTOMER, MIXTURE CONTAINING PERFLUOROELASTOMER AND INDUSTRIAL PRODUCT Russian patent published in 2007 - IPC C08F214/26 C08F214/16 C08L27/18 

FIELD: polymer materials.

SUBSTANCE: invention relates to fluoroelastomers showing excellent combination of mechanical properties, residual compaction, and low-temperature properties as well as to process of production thereof. Curable fluoroelastomers are obtained via polymerization of following monomers: hydrogenated fluoro-C₂-C₈-olefins, fluorovinyl ethers of general formula CFX=CXOCF₂OR (I), bis-olefins having general formula , and optionally one or more fluorinated olefin comonomers selected from perfluoroalkylvinyl ethers CF₂=CFOR² _f, perfluorooxyalkylvinyl ethers CF₂=CFOX^a, perfluoro-C₂-C₈-olefins, one or more non-fluorinated C₂-C₈-olefin, wherein indicated fluoroelastomers contain iodine and/or bromine atoms in their chains and/or terminal chain groups. Fluoroelastomer mixtures cured with peroxide or ionic method and containing above fluoroelastomers as well as industrial products are also described.

EFFECT: improved mechanical and elastic properties of fluoroelastomers, increased resistance to low temperatures, and increased yield of fluoropolymer expressed in kg polymer/h*liter water.
