Embodiment 1

[0158] In the preparation of palladium acetate, trifluoroacetic acid and ((2,2-dimethyl-1,3-dioxane-5,5-diyl)bis(methylene))bis(bis(2-methoxy A linear alternating polyketone terpolymer comprising carbon monoxide and ethylene and propylene is prepared in the presence of a catalyst composition formed from (phenylphenyl)phosphine). In the obtained polyketone terpolymer, the molar ratio of ethylene and propylene was 46:4. In addition, the melting point of the polyketone terpolymer is 220° C., the LVN measured by HFIP (hexafluoroisopropanol) at 25° C. is 1.4 dl / g, and the MI (melt index) is 48 g / 10 min. 90% by weight of the polyketone terpolymer prepared above and 10% by weight of silicone were formed on an extruder using a twin-screw screw with a diameter of 2.5 cm and L / D=32 running at 250 rpm as The pellets were subsequently injection molded to fabricate samples of OA wear parts.

Embodiment 2

[0160] Same as Example 1 except that the polyketone composition consisted of 90% by weight polyketone and 10% by weight polytetrafluoroethylene.

Embodiment 3

[0162] Same as Example 1 except that the polyketone composition consisted of 90% by weight polyketone and 10% by weight glass fibers.
