Provided is a resin composition having excellent heat resistance and water vapor barrier properties. The resin composition contains a resin-containing matrix and a rubber-containing domain, and is characterized in that the resin composition contains a rubber cross-linking agent, and when the torque when a rubber kneaded product obtained by kneading rubber and the rubber cross-linking agent is heated at 200 DEG C and 230 DEG C for 10 minutes is measured over time using a vibratory vulcanization testing machine, the torque of the rubber kneaded product is less than the torque of the rubber cross-linking agent when the rubber kneaded product is heated at 200 DEG C and 230 DEG C for 10 minutes. The torque S '10 min, 200 DEG C after 10 minutes at 200 DEG C is 3.0 dN.m or more, and the relationship of S' 10 min, the torque S '10 min after 10 minutes at 200 DEG C and 230 DEG C, the maximum value S' MAX, 200 DEG C of the torque for 0-10 minutes at 230 DEG C and 200 DEG C, and the maximum value S 'MAX, 230 DEG C of the torque for 0-10 minutes at 230 DEG C satisfies S' 10 min, 200 DEG C/S 'MAX, 200 DEG C > = 0.9 and S' 10 min, 230 DEG C/S 'MAX, 230 DEG C > = 0.9.
提供一种耐热性和水蒸气阻隔性优异的树脂组合物。树脂组合物含有含树脂的基体和含橡胶的结构域,其特征在于,树脂组合物含有橡胶交联剂,在使用振动式硫化试验机经时地测定将混炼有橡胶和橡胶交联剂的橡胶混炼物以200℃和230℃加热10分钟时的转矩时,200℃下10分钟后的转矩S’10min,200℃为3.0dN·m以上,并且S’10min,200℃、230℃下10分钟后的转矩S’10min,230℃、200℃下0~10分钟的转矩的最大值S’MAX,200℃、以及230℃下0~10分钟的转矩的最大值S’MAX,230℃的关系满足S’10min,200℃/S’MAX,200℃≥0.9和S’10min,230℃/S’MAX,230℃≥0.9。
