PROBLEM TO BE SOLVED: To provide a norbornene-based resin composition having excellent rigidity, heat resistance, heat aging resistance, chemical resistance, solvent resistance, dielectric properties, etc., and particularly excellent impact strength and excellent transparency. And its molded articles. SOLUTION: [A] An ethylene-norbornene random copolymer obtained by copolymerizing ethylene and a norbornene represented by the formula [I] shown in the claim [A- 1], a ring-opened polymer or copolymer of the norbornenes [A -2], the hydride [A-3] of the above [A-2] ring-opening polymer or copolymer, and the above [A-1], [A-2] or [A-3] A norbornene-based resin selected from the graft-modified product [A-4] of the above; a difference Δn D in refractive index between 60 to 99 parts by weight and [B] the norbornene-based resin [A] measured at room temperature is 0.0. 3. The norbornene-based resin composition according to the present invention, comprising: an aromatic vinyl / conjugated diene-based elastomer of not more than 3; and 40 to 1 part by weight. Press-through packs, blister packs, packaging sheets, films or packages comprising the composition. |
