摘要
The present invention relates to a process for producing a propylene polymer composition, which comprises preparing a colored layer comprising a propylene polymer composition (A) and a transparent layer-containing film or plate laminated with the propylene polymer composition (A);Heating the laminated film or sheet;;Supplying the heated laminated film or sheet to a mold having a die pair;;Molding the laminated film or sheet into a desired shape by closing the mold;;A step of releasing the closed mold;;And injecting the thermoplastic polymer into the colored layer side of the mold to integrate the molded laminated film or sheet with the base layer of the thermoplastic polymer. The propylene polymer composition is obtained by mixing a polypropylene block copolymer and / or a polypropylene random copolymer exhibiting a specific intrinsic viscosity, polyethylene having a specific intrinsic viscosity, an elastomer having a specific intrinsic viscosity of an -olefin and ethylene, In a certain ratio.;The method can provide an automotive exterior part that exhibits the same colored appearance and texture as the painted exterior part, regardless of the coating process.
