The present invention provides an electrically insulating resin composition comprising a polysulfone resin including a plurality of sulfonyl groups in the molecule and a polyamide resin, wherein the proportion of the polyamide resin is 1 to 45% by mass. The present invention also provides a laminate sheet obtained by bonding a plurality of sheet materials with a resin composition layer interposed therebetween, wherein the resin composition layer comprises a polysulfone resin including a plurality of sulfonyl groups in the molecule and a polyamide resin, and the proportion of the polyamide resin is 1 to 45% by mass.

Electrically insulating resin composition and laminate sheet

The electrolyte membrane of the present disclosure includes a phase A forming a matrix phase, and a phase B. The phase B is continuous from a first principal surface of the electrolyte membrane to a second principal surface of the electrolyte membrane opposite to the first principal surface. The phase B includes a graft polymer having a main chain and a graft chain. The graft chain has a functional group having anion-exchange ability. The main chain preferably has no functional group having anion-exchange ability. The electrolyte membrane of the present disclosure can reliably maintain the function as a separation membrane even when decomposition reaction by a peroxide occurs.
