Abstract

Le séchage de particules polymères vésiculés humides dans de l'air chaud jusqu'à 110 degrés C tend à en altérer la coloration, à introduire des agrégats dans le produit, à affaiblir l'aptitude à la dispersion de ce dernier et à endommager la surface des particules. Le procédé de l'invention comprend le chauffage, à une température élevée, des particules humides dans une atmosphère sans oxygène pour dégager l'humidité des particules en des temps et à des températures réduisant au minimum toute déterioration sensible des particules. L'atmosphère est nitrogen de préférence.
