The instant invention pertains to the use of secondary sterically hindered amines as processing additives in rotational molding processes. These additives increase process stability, since they provide a broader temperature range towards higher temperatures during the melt processing step.
La présente invention concerne l'utilisation d'amines secondaires à encombrement stérique en tant qu'additifs de traitement dans des procédés de moulage rotationnel. Ces additifs accroissent la stabilité du traitement car ils permettent d'utiliser une gamme de températures plus large vers les températures élevées durant l'étape de traitement de la masse fondue.
