CONTROLLING CROSSLINKING DENSITY AND PROCESSING PARAMETERS OF PHTHALONITRILES
20170001357 · 2017-01-05 · ·

Disclosed is a composition having: a diphthalonitrile compound having at least two phthalonitrile groups; a reactive plasticizer; and an amine curing agent. Also disclosed is a composition having: a diphthalonitrile compound having at least two phthalonitrile groups; a nonreactive plasticizer; and an amine curing agent. Also disclosed is a method of: providing a composition having a phthalonitrile compound; heating the composition to a processing temperature until the composition has a viscosity of 30-40 Pas at the processing temperature to form a partially cured composition; placing the partially cured composition into a material chamber of an extrusion machine; heating the partially cured composition and the material chamber to within 10 C. of the processing temperature; and extruding fiber from the extrusion machine.
