Beschreibung
Zusammenfassung:	The present invention discloses a reactive hot melt adhesive composition. This reactive hot melt adhesive composition contains a urethane prepolymer which contains a polymer chain that has a structural unit derived from a polyol including a polyester polyol and a structural unit derived from a polyisocyanate, and an isocyanate group that serves as an end group of the polymer chain. The polyester polyol includes a polyester polyol which has a structural unit derived from a divalent aliphatic carboxylic acid and a structural unit derived from a divalent aliphatic alcohol, wherein at least one of the divalent aliphatic carboxylic acid and the divalent aliphatic alcohol has a tertiary carbon atom or a quaternary carbon atom in each molecule. La présente invention concerne une composition adhésive thermofusible réactive. Cette composition adhésive thermofusible réactive contient un prépolymère d'uréthane qui contient une chaîne polymère qui a une unité structurale dérivée d'un polyol incluant un polyester polyol et une unité structurale dérivée d'un polyisocyanate, et un groupe isocyanate qui sert de groupe terminal de la chaîne polymère. Le polyester polyol comprend un polyester polyol qui a une unité structurale dérivée d'un acide carboxylique aliphatique divalent et une unité structurale dérivée d'un alcool aliphatique divalent, au moins l'un de l'acide carboxylique aliphatique divalent et de l'alcool aliphatique divalent ayant un atome de carbone tertiaire ou un atome de carbone quaternaire dans chaque molécule. 反応性ホットメルト接着剤組成物が開示される。当該反応性ホットメルト接着剤組成物は、ポリエステルポリオールを含むポリオールに由来する構造単位及びポリイソシアネートに由来する構造単位を有する重合鎖を含み、重合鎖の末端基としてイソシアネート基を有する、ウレタンプレポリマーを含有する。ポリエステルポリオールは、脂肪族二価カルボン酸に由来する構造単位及び脂肪族二価アルコールに由来する構造単位を有するポリエステルポリオールであって、脂肪族二価カルボン酸及び脂肪族二価アルコールの少なくとも一方の分子内に、第３級炭素原子又は第４級炭素原子を有するポリエステルポリオールを含む。
