  • Patent number: 10336925
    Abstract: Semi-crystalline polyester polyols and their use in reactive hot-melt adhesives are disclosed. The polyols comprise recurring units of a C2-C10 aliphatic diol, a C8-C24 aliphatic dicarboxylic acid, and 1 to 20 wt. % of an aromatic dicarboxylic acid source, a polycarbonate, or a combination thereof. The polyols have a hydroxyl number within the range of 14 to 112 mg KOH/g. Reactive hot-melt adhesives from the polyols and composite structures produced using the adhesives are also disclosed. A minor proportion of aromatic dicarboxylic acid, polycarbonate content in the polyester polyol surprisingly improves the properties of reactive hot-melt adhesives when compared with a commercial hot-melt adhesive or an adhesive formulated using an all-aliphatic polyester polyol. The adhesives are useful for bonding a wide variety of substrates, including paper, wood, glass, ceramics, plastics, and metals.
