REACTIVE HOT MELT ADHESIVE COMPOSITION, ADHESIVE BODY AND METHOD FOR

The invention discloses a reactive hot melt adhesive composition. The reactive hot-melt adhesive composition contains a polyurethane prepolymer, the polyurethane prepolymer contains a polymer chain and has an isocyanate group as a terminal group of the polymer chain, and the polymer chain has a structural unit derived from a polyol including a polyester polyol and a structural unit derived from a polyisocyanate. The polyester polyol has a structural unit derived from an aliphatic dicarboxylic acid and a structural unit derived from an aliphatic diol, and has a tertiary carbon atom or a quaternary carbon atom in the molecule of at least one of the aliphatic dicarboxylic acid and the aliphatic diol. 本发明公开有一种反应性热熔黏合剂组合物。该反应性热熔黏合剂组合物含有聚氨酯预聚物，所述聚氨酯预聚物包含聚合物链，并且具有异氰酸酯基作为聚合物链的末端基，所述聚合物链具有来自于包含聚酯多元醇的多元醇的结构单元及来自于聚异氰酸酯的结构单元。聚酯多元醇具有来自于脂肪族二元羧酸的结构单元及来自于脂肪族二元醇的结构单元，并且在脂肪族二元羧酸及脂肪族二元醇的至少一者的分子内具有叔碳原子或季碳原子。
