    Abstract: A rubber elastic block copolymer has at least one block A made of polymerise d units of a vinyl aromatic monomer that forms a hard phase and/or a block B with diene monomers that forms a first rubber elastic (soft) phase, and at least one elastomer block B/A with polymerised units of both a vinyl aromatic monomer and a diene that for ms if required a second or additional soft phase. The glass transition temperature T g of block A is higher than 25 .degree.C and that o f blocks B or B/A is lower than 25 .degree.C. The phase volume ratio between blocks A and B/A is selected so that the hard phase represents 1 - 40 % by volume of the total block copolymer and the diene amounts to less than 50 % by weight.

The glass transition temperature Tg of block A is higher than 25 ~C and that of blocks B or B/A is lower than 25 ~C. The phase volume ratio between blocks A and B/A is selected so that the hard phase represents 1 - 40 % by volume of the total block copolymer and the diene amounts to less than 50 % by weight.
