摘要

•Bio-based vanillin oxime and soybean oil polyol were used for the preparation of polyurethane.•Dynamically cross-linked polyurethane hot-melt adhesive (DPU) were constructed with reversible oxime-carbamate bonds.•High adhesive strength and high biomass content were achieved simultaneously.•DPU also displayed excellent low temperature resistance, solvents resistance, and adaptability.
