Composite parts of firmly bonded molding materials, comprising a thermoplastic material containing polyphenylene ether, a layer of SBR or SBS rubber or a mixture thereof surrounding the thermoplastic material, if necessary, an intermediate layer comprising a powdered SBR rubber which may contain a filler, and a rubber containing carbon-carbon double bonds covulcanized with the layer of SBR or SBS rubber. The invention also provides a method for producing the composite part comprising treating the thermoplastic material with a solution of a SBR or SBS rubber in an organic solvent or with an aqueous latex of the rubber, if necessary, completely or partially removing the organic solvent or water, if necessary, treating the dried mass with a powdered SBR rubber which may contain a filler, and covulcanizing with a rubber containing carbon-carbon double bonds.
