Abstract
A method and compositions are described which improve extrusion- and creep-resistance of components for use in a high temperature applications including sealing elements and seal connectors among others. The method includes providing a composition having an aromatic polymer and a crosslinking compound, and subjecting the composition to a heat molding process to form the component and crosslink the aromatic polymer.
