  • Publication number: 20170022331
    Abstract: Disclosed herein is a composition comprising a crosslinked organic polymer; wherein the composition has a coefficient of friction that is in a range of ±30% of a coefficient of friction for a composition comprising the same organic polymer that is not crosslinked; and wherein the composition has a lower K factor than a K factor of the 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.

  • Publication number: 20110213098
    Abstract: An article that includes a thermoplastic composition and a crosslinking agent. The crosslinking agent is thermally activated by annealing at a temperature proximate to the flow point of the thermoplastic composition to stabilize the dimensions of the article during service when compared with a similar article that contains the thermoplastic resin without the crosslinking agent or a similar article that contains the crosslinking agent but is thermally activated at a rate of greater than or equal to about 5 degrees centigrade per minute to the same temperature.
