Abstract: The present invention relates to a vulcanizable composition comprising a specific block copolymer thermoplastic elastomer, a polyolefin, a rubber softener, a crosslinking agent and a specified liquid diene rubber crosslinking co-agent, and a dynamically vulcanized composition produced by intimately mixing the above components under shear and at elevated temperature, which dynamically vulcanized composition is thermoplastic, elastic and moldable.
