Abstract: A material based on polymer(s), the material being surface treated by ion bombardment in order to improve the surface appearance of the material. The invention also relates to a process for obtaining this part and the use thereof, in particular for the manufacture of lighting and/or signaling devices.

Abstract: An apparatus for treating an object, for example an object made of polymer for a light or headlamp of an automotive vehicle, comprises a vacuum chamber in which the object is intended to be placed; means for placing the chamber under vacuum; and ion bombardment means intended for treating the object, comprising an ion generator and at least one ion applicator intended to emit an ion beam. This apparatus comprises, in addition: a first airlock; means for selectively placing the vacuum chamber in communication with the first airlock and means for placing the first airlock under vacuum. The ion bombardment means are arranged outside of the vacuum chamber. The ion applicator is housed in the first airlock.

Abstract: A motor vehicle part comprising a material based on polymer(s), the material being surface treated by ion bombardment in order to improve the surface appearance of the material. The invention also relates to a process for obtaining this part and the use thereof, in particular for the manufacture of lighting and/or signaling devices.

Abstract: The present invention relates to a thermoplastic composition, said composition comprising at least one non-PVC thermoplastic matrix and at least one copolymer chosen from the group consisting of acrylic-based copolymer having an average molecular weight Mw below 400.000 g/mol and acrylic-styrene-based copolymer. The present invention also relates to a process for manufacturing an article from such a thermoplastic composition and to an article obtained from such a thermoplastic composition.
