[formule mathématique (1)] 1,0682 * X + 0,51 < Y < 1 < 1,0682 * X + 1,2 (dans la formule mathématique (1), X représente la teneur en silicone (% en poids) par rapport au poids total de copolycarbonate et de polycarbonate, et Y représente la valeur d'intensité Fid, obtenue par l'intermédiaire d'un test de Fid à domaine temporel (TD), normalisée à 0,1 msec). Une composition de résine de copolycarbonate selon la présente invention présente une excellente mobilité, et présente diverses excellentes propriétés physiques.
