Abstract
Des poudres de polymères de condensation pour fabrication additive peuvent être obtenues par émulsification de monomères de condensation, des intermédiaires des monomères tels que des oligomères ou des sels dans une huile à haute température, l'émulsion étant chauffée à une température de polymérisation à une température supérieure à la température de fusion du polymère pour polymériser et réaliser des particules ayant la forme des gouttelettes émulsifiées lors du refroidissement après polymérisation.
