AN OBJECT OF THE PRESENT INVENTION IS TO PROVIDE A THERMOPLASTIC ELASTOMER COMPOSITION WHICH IS HIGHLY FLEXIBLE WHILE MAINTAINING VIBRATION DAMPING PROPERTIES, AS A FEATURE OF AN ISOBUTYLENE POLYMER, AND IS EXCELLENT IN MOLDABILITY AND RUBBER-LIKE PROPERTIES, AND ALSO HAS PARTICULARLY IMPROVED PERMANENT COMPRESSION SET. THE OBJECT IS ACHIEVED BY A THERMOPLASTIC ELASTOMER COMPOSITION COMPRISING (A) A COMPOSITION OBTAINED BY CROSSLINKING AN ISOBUTYLENE POLYMER HAVING AN ALKENYL GROUP AT THE MOLECULAR ENDS WITH A HYDROSILYL GROUP-CONTAINING COMPOUND WHILE MELT-KNEADING IN THE PRESENCE OF AT LEAST ONE KIND SELECTED FROM AN AROMATIC VINYL-CONTAINING THERMOPLASTIC ELASTOMER AND AN OLEFINIC RESIN, AND (B) AT LEAST ONE KIND SELECTED FROM THE GROUP CONSISTING OF AN AROMATIC VINYL-CONTAINING THERMOPLASTIC ELASTOMER AND AN OLEFINIC RESIN.
