ADHESIVE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain an adhesive resin composition excellent in high-temperature processability and having good adhesion even to a resin without having a polar group or a reactive functional group on the structure such as polystyrene. SOLUTION: This adhesive resin composition comprises 50-99 wt.% of an ethylene-α-olefin copolymer and 1-50 wt.% of a hydrogenated petroleum resin and has 0.865-0.975 g/cm<3> density of the adhesive resin composition or the adhesive resin composition is obtained by compounding 5-99 wt.% of the adhesive resin composition with 1-95 wt.% of a low-density polyethylene resin and has 0.865-0.945 g/cm<3> density of the resin composition. Furthermore, the adhesive resin composition is prepared by compounding 100 pts.wt. of the adhesive resin composition with 1-50 pts.wt. of a polymer completely or partly incompatible with the adhesive resin composition and has 0.875-1.175 g/cm<3> density of the resin composition.
