ABSTRACT:
A multilayered molding is disclosed, which has a base molding outer layer mainly composed of a partial crosslinking type substance A obtained from polyolefin resin and ethylene-.alpha.-olefin copolymer rubber or a mixture B of polyolefin resin and ethylene-.alpha.-olefin copolymer rubber or both. The outermost layer is in direct contact with and forms a lamination with an inner intermediate layer or a base molding composed of a polyethylene resin, for instance, and is firmly bonded to the outermost layer. A method of manufacturing such multilayered molding is also disclosed, in which a composite sheet of the thermoplastic elastomer with or without the intermediate layer is preliminarily heated, followed by being suction held in close contact with a mold cavity inner surface, thus forming a surface layer. The mold is then clamped, and fluidized and plasticized polyolein resin is injected to produce the molding. The polyolefin resin may also be injected prior to the clamping.
