Beschreibung
Zusammenfassung:	In an additive for an epoxy adhesive and a composition for a structural epoxy adhesive including the same, the additive for the epoxy adhesive is an arm-polymer, which is a polyacrylate halogenated at one end and a cross-linker, and a diacrylate compound or a dimethacrylate compound is subjected to atom transfer radical polymerization (ATRP), and includes a star-shaped molding polymer having a core/shell structure comprising a core formed by polymerization of the cross-linker and a shell formed by a portion of the arm-polymer. It is an object of the present invention to provide an additive for an epoxy adhesive capable of improving impact resistance while having a high adhesive strength. 에폭시 접착제용 첨가제 및 이를 포함하는 구조용 에폭시 접착제 조성물에서, 에폭시 접착제용 첨가제는 암-중합체(arm-polymer)로서 일단이 할로겐화된 폴리 아크릴레이트와 가교제(cross-linker)로서 디아크릴레이트계 화합물 또는 디메타아크릴레이트계 화합물이 원자이동라디칼 중합(ATRP)되어 형성하고, 상기 가교제의 중합으로 형성된 코어 및 상기 암-중합체의 일부가 형성하는 쉘을 포함하는 코어/쉘 구조를 갖는 별모양(star-shape)의 성형 중합체를 포함한다.
