Abstract

L'invention est relative à un procédé de préparation de copolyamides pulvérulentes à base de laurolactame. On soumet d'abord les copolyamides obtenues par polymérisation hydrolytique à un traitement d'orientation des molécules, les broie ensuite à basse température et ajuste la granulométrie des poudres obtenues à une valeur de 30 à 100 mu m pour 70 % et de zéro à 30 mu m pour 30 %. Les poudres obtenues peuvent être utilisées pour le revêtement protecteur de récipients en verre.The invention relates to a process for preparing pulverulent copolyamides based on laurolactam. The copolyamides obtained by hydrolytic polymerization are first subjected to an orientation treatment of the molecules, then crushed at low temperature and the particle size of the powders obtained is adjusted to a value of 30 to 100 mu m for 70% and from zero to 30 mu m for 30%. The powders obtained can be used for the protective coating of glass containers.
