Abstract
Polyketone polymers are cured by exposure to high energy radiation. Radiation sources include gamma radiation sources such as Co.sup.60 emitters as well as e-beam, ion and other commercially used sources of high energy radiation. The materials so produced are high molecular weight crosslinked polyketone polymers which exhibit enhanced mechanical and tribological properties.
Claims11
A method of crosslinking alternating aliphatic polyketone polymer consisting essentially of exposing said polyketone polymer to high energy radiation in the substantial absence of oxygen until said polymer undergoes crosslinking reactions.
