(57) [Summary]nThe hot-melt processable adhesive composition such as the pressure-sensitive adhesive (PSA) or the heat-activatable adhesive of the present invention has a wide range of formulation flexibility, and when used for high-performance applications, has a sufficient cohesive strength after application. Show The hot melt processable adhesive of the present invention contains at least one block copolymer containing at least two A blocks and at least one B block. The A and B blocks are derived from monoethylenically unsaturated monomers, which form a saturated polymer backbone that does not require subsequent hydrogenation during polymerization. Preferably, the block copolymer is a (meth) acrylate block copolymer. |
