The invention relates to a thermoplastic polymerncomposition comprising 100 parts by weight of a block copolymernand/or its hydrogenate having polymer blocks of an aromaticnvinyl compound and polymer blocks of a conjugated dienencompound, and from 5 to 95 parts by weight of a block copolymernhaving polymer blocks of an aromatic vinyl compound and/or annolefinic compound and polymer blocks having a constitutionalnunit derived from a (meth)acrylic compound; to a laminatencomprising a layer of the composition and a layer of some othernmaterial; and to a hot-melt adhesive comprising the composition.nAs having good melt adhesiveness, the composition of theninvention can firmly adhere in melt to various polar ornnon-polar materials. Using the composition, it is easy tonproduce laminates comprising a layer of the composition andna layer of some other material, through melt shaping or anynother melt adhesion techniques. Since the composition of theninvention is satisfactorily elastic and flexible, thenlaminates having a layer of the composition on their surfacenare flexible and elastic and have a good feel, and, in addition,nthey are highly safe because of their shock absorbability andncushionability. |
