MUTILAYER MOLDED ARTICLES AND PROCESS FOR PRODUCING THE SAME |
摘要 |
A multilayer molded article comprising a skin and a substrate consisting of a polypropylene resin composition having a crystallization rate of 45 second or less, said skin being integrally adhered to the substrate. Said multilayer molded article can be pro- duced by feeding a skin material and a molten polypro- pylene resin composition having a crystallization rate of 45 second or less between a pair of upper and lower molds, molding the molten polypropylene resin composi- tion in the molds with simultaneous adhering of the skin material to the surface of the molded resin composition and then cooling the molten resin composition to solid- ify the same. Said multilayer molded article has a small deformation degree without the soft feeling of the skin material being impaired.
