    Abstract: PROBLEM TO BE SOLVED: To provide a two-pack reactive type adhesive having adhesive strength compatible with long-term durability. SOLUTION: A principal ingredient of the two-pack reactive type polyurethane-based adhesive has a terminal OH group. The principal ingredient is obtained by reacting a polycarbonate polyol A having a diol unit containing 20-100 mol% of a diol having a branched alkyl side chain, and having 400-8,000 weight-average molecular weight with an alkylenediol chain extender B having 62-300 molecular weight, and an organic diisocyanate C in an equivalent ratio NCO/OH=0.7-0.99. The two-pack reactive type polyurethane-based adhesive is provided by using the principal ingredient. COPYRIGHT: (C)2010,JPO&INPIT
