WIPO Patent Application WO/2024/069999

A1

Provided is a resin composition having excellent heat resistance and water vapor barrier properties. The resin composition comprises a matrix containing a resin and a domain containing a rubber the resin composition being characterized in that: the resin composition includes a rubber crosslinking agent; and when the torque, at which a rubber kneaded material obtained by kneading the rubber and the rubber crosslinking agent is heated at 200°C and 230°C for 10 minutes, is measured over time using a vibration-type vulcanization tester, the torque S'10min, 200°C at 200°C after 10 minutes is at least 3.0 dN·m, and S'10min, 200°C, the torque S'10min, 230°C at 230°C after 10 minutes, the maximum torque S'MAX, 200°C at 200°C for 0-10 minutes, and the maximum torque S'MAX, 230°C at 230°C for 0-10 minutes satisfy S'10min, 200°C／S'MAX, 200°C≥0.9 and S'10min, 230°C／S'MAX, 230°C≥0.9.
