“…Adhesives serve a crucial part in human life and are extensively utilized in the industrial bonding, packaging, building manufacturing, electronic device, and aerospace industries. − However, at present, adhesives still face challenges such as poor bond strength (such as epoxy resins), − toxicity, irreversible curing (such as acrylics, polyurethanes, and organic silicones), , and limited conditions of use (such as anaerobic adhesives, UV adhesives, and solvent-based adhesives). − Polyester hot-melt adhesives are a typical example of solvent-free, ecologically friendly adhesives that meet the demands of the adhesive industry for energy efficiency, nontoxicity, low cost, reusability, and excellent performance. , Linear saturated polyesters are generally utilized as hot-melt adhesives, prepared by transesterification, esterification, and polycondensation reactions, which is simple and easy to process. − However, these raw materials used in commercial hot-melt adhesives are usually derived from petroleum resources and do not meet the requirements of sustainable development. − Yet, compared to petrochemical products, which come in a large variety, the number of biobased monomers that can be employed to create biomass polyester hot-melt adhesives is substantially fewer. − For example, Zheng et al used biobased 1,5-pentanediol as a replacement for petroleum-derived 1,6-hexanediol for polyester hot-melt adhesives . Kim et al prepared a polyester hot-melt adhesive using polybutylene terephthalate modified with dimer acid methyl ester derived from fatty acid methyl esters .…”
