| 摘要 |
The present invention pertains to a resin composition for a solid polymer fuel cell sealing material, wherein the resin composition contains a copolymer resin which is obtained by copolymerizing raw material components including (a1) 5 mass% or more of styrene and (b) 20 mass% or less of glycidyl(meth)acrylate and has a weight-average molecular weight of 150,000 or more. Preferably, the raw material components are configured to further contain (c) at least one other kind of polymerizable monomer selected from hydroxyalkyl(meth)acrylate and alkyl(meth)acrylate. |
