    摘要： 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.

    摘要翻译： 公开了半结晶聚酯多元醇及其在反应性热熔粘合剂中的用途。 多元醇包括C 2 -C 10脂族二醇，C 8 -C 24脂族二羧酸和1至20重量％的重复单元。 ％的芳族二羧酸源，聚碳酸酯或其组合。 多元醇的羟值在14至112mg KOH / g的范围内。 还公开了使用粘合剂制备的多元醇和复合结构的活性热熔粘合剂。 当与商业热熔粘合剂或使用全脂族聚酯多元醇配制的粘合剂相比时，少量的芳族二羧酸，聚酯多元醇中的聚碳酸酯含量令人惊奇地改善了反应性热熔粘合剂的性能。 粘合剂可用于粘合各种基材，包括纸，木材，玻璃，陶瓷，塑料和金属。

    摘要： The present invention relates to coatings, particularly high performance coatings, containing a polyester polyol comprising recurring units derived from a polyacid source, poly(bisphenol-A carbonate) (PBAC), and a glycol. The PBAC is preferably recycled poly(bisphenol-A carbonate) (rPBAC). These coatings provide improved salt spray and stain resistance along with a variety of other coating performance attributes. The polyols can contain a significant recycle and biobased content, making them sustainable alternatives to petroleum based polyols.
