Abstract
Provided is a resin composition for a solid polymer fuel cell sealing material, the resin composition including a copolymer resin having a weight average molecular weight of 150,000 or more and formed by copolymerizing raw material components including: (a1) 5% by mass or more of styrene; and (b) 20% by mass or less of glycidyl (meth)acrylate. Preferably, the raw material components are configured to further include (c) one or more kinds of other polymerizable monomers selected from a hydroxyalkyl (meth)acrylate and an alkyl (meth)acrylate.
