Problems solved by technology

However, molding compositions based on molding color systems must have high UV stability. For this reason, impact modifiers based on rubbers with conjugated dienes, for example, butadiene in ABS or MBS rubbers cannot Use alone

Abstract

The invention relates to coloured, weather-resistant compositions based on polyalkylene terephthalate / polycarbonate blends with modified impact resistance. The invention also relates to moulding materials, semi-finished products and moulded parts, which are produced from the same and are used in an unlacquered state or coated only with a transparent clear lacquer, for example, in exterior automotive applications.

Description

technical field [0001] The invention relates to pigmented, weather-resistant and stable compositions based on impact-modified polyalkylene terephthalate / polycarbonate blends, as well as molding compositions, semi-finished products and molded parts produced therefrom, which In the unpainted state or only with a clear varnish, it is used, for example, in the automotive exterior sector. Background technique [0002] Impact-modifying molding compositions comprising partially crystalline polyesters, amorphous polycarbonates and graft copolymers are known. Such molding compositions are used, for example, in the automotive sector for molded parts such as bumpers, fenders, radiator grilles, headlight glasses, rear foldable window glasses, Door sills, spoilers, door handles, fuel tank caps, linings, horizontal structural components such as hood covers, or roof components, door components, etc. Prerequisites for use in automotive applications are high heat distortion point, high mel...
