Abstract

Utilisation d'une matière moulable thermoplastique, différente de l'acylnitrile/butadiène/styrol (ABS), qui comprend, par rapport à la somme des quantités des constituants A, B, C et éventuellement D et E, représentant au total 100 % en poids: (a) de 1 à 48 % en poids d'au moins un polymérisat par émulsion particulaire à une ou plusieurs phases présentant une température de transition vitreuse inférieure à 0 °C pour une phase au moins et une taille moyenne des particules de 50 à 1000 nm, de préférence de 50 à 500 nm en tant que constituant A; (b) de 1 à 48 % en poids d'au moins un polymérisat amorphe ou partiellement cristallin en tant que constituant B; (c) de 51 à 98 % en poids de polycarbonate en tant que constituant C; et (d) de 0 à 47 % en poids d'additifs courants et/ou de charges particulaires ou fibreuses ou de leurs mélanges en tant que constituant D; et (e) de 0 à 5 % en poids d'au moins un acide de faible poids moléculaire et exempt d'halogène en tant que constituant E, en tant que matière moulable résistante au gonflement pour la fabrication d'éléments de carrosserie et de leurs demi-produits pour des véhicules. La présente invention concerne également des matières moulables exemptes de charge contenant a, b, c et e à raison de 0,05 à 2 % en poids, ainsi que les éléments moulés, feuilles et fibres fabriqués à l'aide desdites matières.
