An adhesive composition which is the crosslinked product of components which comprise (C) a copolymer of a (meth)acrylic ester having a weight-average molecular weight of 1,000,000 or greater, (D) 5 to 100 parts by weight per 100 parts by weight of component (C) of an oligomer of (meth)acrylic esters having a weight-average molecular weight of 1,000 to 10,000 and (E) 0.001 to 50 parts by weight per 100 parts by weight of component (C) of a crosslinking component comprising a difunctional crosslinking agent. The adhesive composition exhibits excellent adhesion with adherents, and stress relaxation and follows changes in the dimensions of substrates.
一种粘合剂组合物,它是各组分的交联产物,这些组分包括:(C) 重量平均分子量为 1,000,000 或更大的(甲基)
丙烯酸酯共聚物;(D) 重量平均分子量为 1,000 至 10,000 的(甲基)
丙烯酸酯低聚物(以每 100 份组分(C)的重量计)为 5 至 100 份;以及(E) 以每 100 份组分(C)的重量计,含有双官能团
交联剂的交联组分为 0.001 至 50 份。该粘合剂组合物与附着物具有极佳的粘合力,应力松弛并随基材尺寸的变化而变化。
