Provided are: a resin composition for a gasket, said resin composition being used as a material for a gasket used in a sealed secondary battery (storage battery) such as a lithium ion secondary battery, and exhibiting excellent cavity balance and a high mechanical strength; a production method for said resin composition; and a gasket for a secondary battery. More specifically, the present invention relates to: a resin composition for a gasket used in a secondary battery configured from a positive electrode, a negative electrode, a sealing body, a gasket, a separator, and an electrolyte, said resin composition including a polyarylene sulfide resin and a silicone compound, and being capable of being obtained using a method including a step in which the polyarylene sulfide resin is subjected to a reaction in a molten mixture including a diiodo aromatic compound, elemental sulfur, and a polymerization inhibitor; a production method for said resin composition; and a gasket for a secondary battery. |
