ABSTRACT:
A thermoplastic elastomeric material comprising a hydrogenated copolymer of a conjugated diene characterised in that the copolymer before hydrogenation is a random copolymer of 70 to 99 mole % of at least one conjugated diene and 30 to 1 mole % of at least one vinyl aromatic compound, is of number average molecular weight of at least 100,000, and has a vinyl content of at most 40 mole % based on total monomers, and in that the copolymer is hydrogenated to an extent such that the mole percentage saturation is in the range 40 to 90%.
