    摘要： A thermoplastic polymer composition is provided that includes 100 parts by weight of a block copolymer and/or its hydrogenate having polymer blocks of an aromatic vinyl compound and polymer blocks of a conjugated diene compound, and from 5 to 95 parts by weight of a block copolymer having polymer blocks of an aromatic vinyl compound and/or an olefinic compound and polymer blocks having a constitutional unit derived from a (meth) acrylic compound, a laminate containing a layer of the composition, and a hot-melt adhesive that includes the composition. Because it has good melt adhesiveness, the composition of the invention can firmly adhere in melt to various polar or non-polar materials. Using the composition, it is easy to produce laminates having a layer of the composition and a layer of some other material, through melt shaping or any other melt adhesion techniques. Since the composition of the invention is satisfactorily elastic and flexible, the laminates having a layer of the composition on their surface are flexible and elastic and have a good feel, and, in addition, they are safe because of their shock absorbability and cushionability.

    摘要： In anionic polymerization using an anionic polymerization initiator, a tertiary organoaluminum compound (A) having in the molecule thereof a chemical structure represented by a general formula: Al—O—Ar wherein Ar represents an aromatic ring, and at least one Lewis base (B) selected from the group consisting of an ether compound and a tertiary polyamine compound are caused to be present in the polymerization system. In this way, the polar monomer can be polymerized with a high polymerization initiation efficiency and a high living polymerization property and at a high polymerization rate even if the used polymerization initiator is suitable for industrial use and a relatively mild cooling condition or a temperature condition near room temperature is adopted as a polymerization temperature condition.
