Abstract: The present invention relates to a process for the production of impact-modified filled polycarbonate compositions and molding compositions. A process of the present invention involves: (i) mixing the CNT (component C) with rubber-containing vinyl copolymer (component B) and/or rubber-free vinyl copolymer (component D) on a twin screw extruder, to obtain a CNT masterbatch, (ii) mixing the CNT masterbatch with polycarbonate (component A) and optionally with Component B and/or Component D and optionally with an additive on a twin screw extruder. A polycarbonate composition prepared according to the present invention does not experience degradation of the molecular weight of the polycarbonate during compounding a compared to processes known in the art.

Abstract: A process for the production of a molded article is disclosed. The process comprise a) placing a plastic film abutting the inside wall of a first half of a mold, said mold including a first and second halves, b) combining said second half with said first half in a manner creating a mold cavity, c) injecting resin into said cavity to produce an article to which surface adherently bonded is said plastic film, d) separating one of the halves from the other half, said article remaining with said other half, e) combining a supplemental half with said other half in a manner forming a gap between the inner wall of said supplemental half and the surface of said molded article, f) injecting lacquer into said gap, g) curing the lacquer to produce a lacquered molded article, and h) cooling and removing the lacquered molded article from the mold. The inventive process is particularly suitable for making vehicular mirrors.
