Claim Text:
1. A crosslinked organic polymer: the crosslinked organic polymer being at a temperature below its glass transition temperature; where the crosslinked organic polymer is a polyacetal, a polyacrylic, a polycarbonate, a polyester, a polyamide, a polyamideimide, a polyarylate, a polyarylsulfone, a polyethersulfone, a polyphenylene sulfide, a polysulfone, a polyimide, a polyetherimide, a polyetherketone, a polyether etherketone, a polyether ketone ketone, a polybenzoxazole, a polyphthalide, a polyanhydride, a polyvinyl ether, a polyvinyl thioether, a polyvinyl alcohol, a polyvinyl ketone, a polyvinyl nitrile, a polyvinyl ester, a polysulfonate, a polysulfide, a polythioester, a polysulfone, a polysulfonamide, a polyurea, a polyphosphazene, a polysilazane, or a combination thereof; where the polyamide is polypyrrolidone, polycaprolactam, polytetramethylene adipamide, polycapryllactam, polyhexamethylene adipamide, polyundecanolactam, polydodecanolactam, polyhexamethylene azelaiamide, polyhexamethylene sebacamide, polyhexamethylene isophthalamide, polyhexamethylene terephthalamide, polyphthalamide, or a combination thereof; wherein a composition comprising the crosslinked organic polymer has a coefficient of friction that is about 10% to about 70% greater than a coefficient of friction for a composition comprising the same organic polymer that is not crosslinked; and wherein a composition comprising the crosslinked organic polymer has a lower K factor than a K factor of a composition comprising the same organic polymer that is not crosslinked; the coefficient of friction and the K factor being measured in a thrust washer apparatus as per ASTM D-3702, where the counter stationary surface in the thrust washer apparatus comprises carbon steel having a Rockwell C hardness of 18 to 22 and a 12 to 16 micro-inch surface finish.
