Zusammenfassung:PROBLEM TO BE SOLVED: To provide a composition available for a structural adhesive.SOLUTION: A composition available for a structural adhesive essentially contains a polymer system suitable for used for a methacrylate matrix, where the polymer system contains a styrene-free block copolymer formed of at least two blocks, preferably, at least three blocks, the polymer system has solubility to a linear or branched acrylic monomer or methacryl monomer, and/or a matrix of cyclic methacrylate and/or aromatic methacrylate. An application is incorporated with blending of an a methacrylic acid type adhesive.SELECTED DRAWING: Figure 1 【課題】構造用接着剤に利用可能な組成物の提供。【解決手段】メタクリル酸エステルマトリックスに用いるのに適したポリマー系を必須に含み、上記ポリマー系は、少なくとも2ブロック、好ましくは少なくとも3ブロックから形成されたスチレンフリーブロック共重合体を含み、上記ポリマー系は、直鎖状若しくは分枝状のアクリルモノマーまたはメタクリルモノマー、並びに/または、環状メタクリル酸エステル及び/若しくは芳香族メタクリル酸エステルのマトリックスに溶解性がある、構造用接着剤に利用可能な組成物。メタクリル酸タイプの接着剤の配合に組み入れることによる用途。【選択図】図1
