本実施例では、金型12のキャビティ部29における表面温度を76℃とした以外は、実施例1と全く同一にして、図1に示す形状のマグカップ1を製造した。
本実施例では、前記樹脂組成物に、該樹脂組成物の0.05重量%の超臨界状態の窒素を含浸させた以外は、実施例1と全く同一にして、図1に示す形状のマグカップ1を製造した。
本実施例では、前記樹脂組成物に、該樹脂組成物の0.3重量%の超臨界状態の窒素を含浸させた以外は、実施例1と全く同一にして、図1に示す形状のマグカップ1を製造した。
本比較例では、前記樹脂組成物に、該樹脂組成物の0.01重量%の超臨界状態の窒素を含浸させた以外は、実施例1と全く同一にして、図1に示す形状のマグカップ1を製造した。
本比較例では、前記樹脂組成物に、該樹脂組成物の0.4重量%の超臨界状態の窒素を含浸させた以外は、実施例1と全く同一にして、図1に示す形状のマグカップ1を製造した。
本参考例では、前記樹脂組成物に超臨界状態の窒素を全く含浸させず、金型12のキャビティ部29における表面温度を110℃とした以外は、実施例1と全く同一にして、図1に示す形状のマグカップ1を製造した。
