<p>A hot melt adhesive composition comprising 100 parts by weight of a tackifier (B) and 1 to 900 parts by weight of an α-olefin/aromatic vinyl random copolymer (C); another hot melt adhesive composition comprising 100 parts by weight of a base polymer (A), 1 to 900 parts by weight of the component (B) and 1 to 1000 parts by weight of the component (C); and still another hot melt adhesive composition comprising 100 parts by weight of the component (A), 10 to 300 parts by weight of the component (B) and 10 to 400 parts by weight of the component (C). The component (A) is preferably at least one polymer selected from the group consiting of (a-1) polyolefins, (a-2) polymers having polar groups and (a-3) aromatic vinyl/conjugated diene copolymers. These adhesive compositions are excellent in adhesive strength and usable also as adhesives for styrene resins.</p> |
