ABSTRACT OF THE DISCLOSURE: Hot-melt pressure-sensitive adhesive com- position based on a rubbery block copolymer of a monovinyl-aromatic compound or monovinylidene-aromatic compound and butadiene. The composition contains a selectively hydrogenated radial block copolymer with terminal polymer blocks of the monovinyl- or mono- vinylidene-aromatic compound and, in the middle position, butadiene- based polymer blocks which had a 1,2-vinyl content of from 30 to 70 per cent by weight prior to hydrogenation. The compositions may be used, in particular, for the production of self-adhesive materials.
