1. produce a method for carbon monoxide-olefin polymeric, described method comprises the steps:

  • A () providing package is containing the first catalyst that is acid, porous crystalline material, described first catalyst has the first proton density, and wherein acid, porous crystalline material is aluminosilicate zeolites;

    B () makes described first catalyst of step (a) and the water of liquid form contact add proton and produce second catalyst with the second proton density under the Contact Temperature of 1 DEG C to 99 DEG C, the value of the second proton density described in wherein when measuring under the same conditions is greater than the value of described first proton density;

    WithC described second catalyst of step (b) to be up under the baking temperature of 550 DEG C dry to remove at least part of described proton and produce the described carbon monoxide-olefin polymeric with the 3rd proton density from described second catalyst by (), the value of the 3rd proton density described in wherein when measuring under the same conditions is between the value and the value of described second proton density of described first proton density.
