HÄRTBARE PERFLUORELASTOMERZUSAMMENSETZUNG |
摘要 |
<p>Perfluoroelastomer compositions comprising perfluoroelastomers having copolymerized units of tetrafluoroethylene, a perfluoro(vinyl ether), and a nitrile-containing cure site monomer are cured with compounds that are capable of generating ammonia at temperatures of 40° C.-330° C. to produce cured compositions having excellent thermal stability. The ammonia-generating compounds also act as cure accelerators in perfluoroelastomer compositions that incorporate other curing agents.</p> |
