  • Yield-optimized method for producing a polyamide powder composition
    Publication number: 20230374217
    Abstract: The present invention relates to a process for preparing a powder composition based on polyamide(s) with an optimized yield. The process includes a step of recycling a composition based on a polyamide prepolymer having a lower Dv50, by polycondensation of a mixture comprising said composition and one or more monomers in the presence of water. The invention also relates to the powder composition obtained and to the use thereof, especially for coating metal substrates by fluidized bed dip-coating.
