Fluoroelastomers based on vinylidene fluoride exhibiting superior resistance to organic bases. |
摘要 |
<p>Fluoroelastomeric copolymers exhibiting high resistance to bases and alcohols, as well as high mechanical properties and low-temperature resistance, comprising, in moles: 4-75% of units of vinylidene fluoride; 12-40% of units of hexafluoropropene and/or perfluorovinylether and/or hydropentafluoropropene and/or chlorotrifluoroethylene; 2-35% of units of an olefin containing up to 4 carbon atoms; 2-60% of units of tetrafluoroethylene, provided that, when the sum of the olefin units and the perfluorovinylether units is equal to or greater than 70%, such copolymers possess a molecular weight sufficiently high to exhibit good mechanical characteristics.</p> |
