Beschreibung
Zusammenfassung:	The purpose of the present invention is to provide an acrylic adhesive which has excellent adhesion strength at high temperatures and gives cured objects having excellent elongation. The provided acrylic adhesive is a two-pack mixing type acrylic adhesive composition which comprises (A) a urethane (meth)acrylate including a lowly crystalline poly(tetramethylene glycol) as a backbone skeleton, (B) a polymerizable vinyl monomer, (C) an organic peroxide, and (D) a reducing agent as essential components. Le but de la présente invention est de fournir un adhésif acrylique qui a une excellente force d'adhésion à des températures élevées et donne des objets durcis ayant un excellent allongement. L'adhésif acrylique selon l'invention est une composition adhésive acrylique de type à mélange à deux composants qui comprend (A) un (méth)acrylate d'uréthane comprenant un poly(tétraméthylène glycol) faiblement cristallin en tant qu'ossature squelette, (B) un monomère vinylique polymérisable, (C) un peroxyde organique, et (D) un agent réducteur en tant que composants essentiels. 本発明は、高温下での接着強度に優れ、かつ硬化物の伸びに優れたアクリル系接着剤を提供することを目的とする。解決手段として、（Ａ）低結晶性ポリテトラメチレングリコールを主鎖骨格とするウレタン（メタ）アクリレート、（Ｂ）重合性ビニルモノマー、（Ｃ）有機過酸化物、（Ｄ）還元剤、を必須成分とする二液混合型アクリル系接着剤組成物を提供する。
