Abstract
A alternating aliphatic polyketone polymer is surface derivatized to alter the surface properties of an article without affecting the bulk properties of the polymer it is made from. Derivitization may be done with reducing agents and/or silylating agents. Articles so produced display a range of improved properties including reduced wettability and improved tribological properties such as lubricity and wear resistance.
