摘要：Reactive polyurethane hot melt adhesives (HMPURs) containing a blend of polyester and polycarbonate diols can typically exhibit balanced performance, such as bonding properties, tensile strength, and heat resistance. Two series of HMPURs made from poly 1,4-butylene adipate or sebacic acid (SeA)-based polyester diols with different molecular weights were prepared and investigated. Increasing the molecular weight of the SeA-based polyester diols was found to significantly improve their mechanical properties and lap shear strengths. Moreover, the HMPURs made from SeA-based polyester diol exhibited better performances than those made from poly 1,4-butylene adipate. Also, the HMPURs were more suitable for bonding on PC substrate.
