Abstract: A biomass-based thermoplastic polyurethane is provided. The biomass-based thermoplastic polyurethane is a reaction product of a composition. The composition includes 1-50 parts by weight of a modified lignin, 50-99 parts by weight of a first polyol, and 40-60 parts by weight of a diisocyanate. The modified lignin has an OH value of less than 3.0 mmol/g. The sum of the modified lignin and the first polyol is 100 parts by weight.

Abstract: A resin is provided, wherein the resin is formed by reacting 1 part by mole of a multi-isocyanate core with 3 to 4.5 parts by mole of diol to form an intermediate, and then reacting the intermediate with 3 to 4.5 parts by mole of first diisocyanate. The multi-isocyanate core can be a multi-isocyanate compound with more than two isocyanate groups. Alternatively, the multi-isocyanate core can be formed by reacting a second diisocyanate with a multi-hydroxy compound, and the multi-hydroxy compound has more than two hydroxy groups.
