Abstract

L'invention porte sur un article moulé en résine aromatique, sur son procédé de fabrication et sur une pastille et une composition pour sa fabrication, comprenant : une résine de polymère, une matière aromatique et un adjuvant de rétention pour la suppression de la volatilisation de la matière aromatique, l'adjuvant de la rétention ayant une compatibilité par rapport à la résine de polymère. L'article moulé en résine de polymère ne présente pas de problèmes comme la volatilisation ou la décomposition de composés aromatiques dans un procédé de traitement, en particulier dans un procédé de traitement à haute température, et préserve d'excellentes stabilité, durabilité et résistance des composés aromatiques. De plus, la dégradation des propriétés physiques dans l'article moulé en résine de polymère peut être empêchée ou supprimée.
