PROBLEM TO BE SOLVED: To obtain a thermoplastic resin composition excellent in moldability and moisture resistance, greatly improved in molding strain, and suitable for sealing by using a thermoplastic aromatic resin and a thermoplastic aromatic norbornene based resin as the constituents. SOLUTION: This composition contains a thermoplastic aromatic resin (A) having aromatic ring(s) in the backbone and a thermoplastic aromatic norbornene based resin (B) comprising, e.g. a ring-opening polymer of an aromatic norbornene monomer, a ring-opening copolymer of an aromatic norbornene monomer, with a nonaromatic norbornene monomer, or an adduct of an aromatic norbornene monomer with an aromatic vinyl compound at a weight ratio of component A to component B of (5:95) to (95:5). If necessary, other synthetic resin, an elastomer, and various additives can be blended with the composition. |
