Abstract:
1. A method of preparing a cured thermoplastic material, comprising: curing a thermoplastic polymer having a thermal decomposition temperature greater than or equal to about 200° C., at a temperature of about 300° C. to about 380° C., in the presence of a crosslinker comprising elemental sulfur, a metal peroxide, or a combination comprising at least one of the foregoing crosslinkers for a total time of less than or equal to 200 hours; wherein the thermoplastic polymer comprises polyphenylene sulfide (PPS), a polyaryletherketone (PAEK), a polyertherether ketone (PEEK), a polyethersulfone (PESU), a polyphenylenesulfone (PPSU), a polyphenylenesulfone urea, or combinations comprising at least at least one of the foregoing.
