摘要： A hot-melt adhesive composition which comprises a modified block copolymer, a paraffin wax having a melting point of 40 to 100 DEG C, a tackifier, and an antioxidant. The copolymer is obtained by epoxidizing carbon-carbon double bonds of conjugated diene units of a block copolymer having in the molecule at least one polymer block (A) formed mainly from a vinylaromatic compound and at least one polymer block (B) formed mainly from a conjugated diene compound. The modified block copolymer has satisfactory compatibility with the paraffin wax and the tackifier because it has epoxy groups, which are polar, in the molecule. Since the modified block copolymer and the paraffin wax are used in combination as the base, the composition has excellent heat and cold resistance and is highly heat-resistant despite its low melt viscosity.
