Verfahren zur Herstellung einer Aussenprofilleiste für Fahrzeuge, laminierte Schicht oder Folie zur Verwendung in diesem Verfahren und eine Aussenprofilleiste für Fahrzeuge

摘要

A method of producing a colored molded product, which method comprises: heating a laminate of a colored layer (I) comprising a propylene polymer composition (A) having a thickness of 150 to 1000 mu m and a clear layer (II) comprising a propylene homopolymer (B) having a thickness of 10 to 100 mu m through which light may be transmitted so that the color of the colored layer (I) may be visible, said propylene polymer composition (A) comprising: (a) 50 to 90% by weight of a polypropylene block copolymer (a1) and/or a polypropylene random copolymer (a2) having an intrinsic viscosity ( eta ), as measured at 135 DEG C in decalin, of 2.0 to 4.0 dl/g, (b) 5 to 45% by weight of a polyethylene having an intrinsic viscosity ( eta ), as measured at 135 DEG C in decalin, of 1.0 to 5.0 dl/g, (c) 5 to 45% by weight of an elastomer comprising a copolymer of ethylene and an alpha -olefin having 3 to 10 carbon atoms, said copolymer having an intrinsic viscosity ( eta ), as measured at 135 DEG C in decalin, of 1.0 to 3.0 dl/g, and (d) 0.1 to 20 parts by weight, per 100 parts by weight of the sum of the components (a), (b) and (c), of a colorant; shaping the heated laminate into the desired configuration; and providing a thermoplastic polymer (C) onto the colored layer (I) of the shaped laminate.
