The invention relates to a process for the preparation of a thermoplastic elastomer (TPE) comprising a blend of polypropylene, polymethylpentene and an at least partially vulcanized rubber. The invention is characterized in that the blend is obtained by dynamically vulcanizing a mixture of the polypropylene, the polymethylpentene and the rubber, in the presence of a vulcanizing agent. The invention also relates to such TPE's with a hardness below 88 Shore A, as well as to shaped objects and foamed articles made therefrom.
