摘要： Hot-melt pressure-sensitive adhesive composition 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.
