A semicrystalline poly ketone powder useful for additive manufacturing may be made by dissolving a polyketone having differential scanning calorimetry (DSC) monomodal melt peak, at a temperature above 50 C. to below the melt temperature of the polyketone, precipitating the dissolved polyketone by cooling, addition of a nonsolvent or combination thereof. The method may be used to form polyketones having a DSC melt peak with an enthalpy greater than the starting polyketone.

The invention provides a high pressure, free-radical polymerization process for polymerizing an ethylene-based polymer, said process comprising polymerizing ethylene, in a reactor configuration comprising a reactor with at least two reaction zones, a first reaction zone and a reaction zone located downstream from the first reaction zone; and wherein CO (carbon monoxide) is added to the reactor in at least one reaction zone located downstream from the first reaction zone, and wherein, less than, or equal to, 95 weight percent of the total amount of CO, is fed to the first reaction zone.
