The severity of plastic pollution has reached a breaking point where a holistic transition is required on every application of plastics. Accordingly, adhesives that are mainly used in industries such as automobiles, textiles, and packaging, also need a substitution owing to their chemical and physical nature. Instead of using excessive petroleum-based materials, biomass-based alternatives can be subjected to give sufficient mechanical properties and biodegradability. Herein, we propose a novel citrate complex polyester system, poly(Isosorbide-co-1,4-cyclohexanedimethanol succinate-co-citrate) (PICSC), consisting of not only biomass monomers but also exhibiting a high adhesion value of 4.5 MPa, which is comparable to conventional hot melt. Owing to an infrastructure created by citric acid, rigid isosorbide, and flexible properties of 1,4-cyclohexanedimethanol and succinic acid, versatile hot-melt adhesive was fabricated with biodegradable, soluble, and mechanically sound properties.
