Banana pseudo-stem was liquefied in the mixture of polyhydric alcohols of polyethylene glycol (PEG400) and glycerol. Hydroxyl value of liquefied products ranged from 294.8 to 370.2 mg KOH/g and Mn was about 430. Liquefied products (LBPP) could be used as raw materials for polyurethane by reacting with 4, 4\'-diphenylmethane diisocyanate (4, 4\'-MDI) and PEG400 to synthesize liquefied product-based polyurethane (LBPP-PU) adhesive. To analyze in depth the creation of urethane linkage among LBPP , PEG400 and 4, 4\'-MDI, factors which had effects on the residue content were all investigated. They were characterized by FT-IR and TG. The shear strength of LBPP-PU adhesive was improved when decreasing the percentage of the substitution of PEG400 by LBPP. The adhesive strength was obtained from T-peel of aspen/polyurethane adhesive joints, and the maximum lap shear strength (4.40 MPa) was obtained when 16.70％ of LBPP was added to the LBPP &PEG400 system.
