Abstract:
A process for preparing a stabilized fabricated article from a polyolefin resin, the process includes incorporating functional groups in the polyolefin resin thereby yielding a polyolefin resin having crosslinkable functional groups. The polyolefin resin having crosslinkable functional groups is converted to a fabricated article. The fabricated article is chemically crosslinked thereby yielding a crosslinked fabricated article. The crosslinked fabricated article is stabilized in an oxidizing environment at an elevated temperature. The stabilized fabricated article thus produced can be prepared as a carbonaceous article by heating the stabilized fabricated article in an inert environment.
