Abstract

La présente invention concerne une composition de résine de polycarbonate antistatique comprenant 100 parties en poids d'un composant de résine et 0,1 à 20 parties en poids d'un sel de phosphonium d'acide sulfonique organique spécifique (C) en tant qu'agent antistatique incorporé dans le composant de résine, le composant de résine comprenant 90 à 99,9 % en poids d'une résine de polycarbonate (A) et 0,1 à 10 % en poids de polycaprolactone (B). La composition de résine de polycarbonate antistatique est dotée d'excellentes propriétés antistatiques sans amoindrir l'excellente transparence de la résine de polycarbonate, ce qui rend son utilisation appropriée dans des composants externes de conditionnement, par exemple pour des appareils de bureaux tels que des cartouches de disques optiques dont les propriétés optiques doivent être élevées, dans lesquels un mauvais fonctionnement peut se présenter par suite de la présence de poussières.
