PURPOSE:To obtain the titled adhesive having excellent adhesiveness to an olefin resin and a styrene resin, by mixing a PP polymer, a specified copolymer, a high-impact polystyrene, and a block copolymer of a vinyl aromatic compound with a conjugated diene. CONSTITUTION:1-20wt% propylene polymer (A) which comprises a (random or block co)polymer of propylene and, if necessary, ethylene or an alpha-olefin is mixed with an ethylene-vinyl acetate copolymer (B) which has a melt flow rate of 0.5-40g/10min and contains 5-35wt% vinyl acetate; 5-30wt% high- impact polystyrene (C) which has an MI of 0.1-50g/10min and is obtained by graft polymerization of styrene with, e.g., a butadiene(-styrene co)polymer rubber; 1-25wt% block copolymer (D) of a vinyl aromatic compound (e.g., styrene) with a conjugated diene (e.g., butadiene) which has an MI of 20g/10min or less; and, if necessary, a stabilizer, a lubricant, a plasticizer, a filler, etc. |
