## Abstract The sulphonated phenol novolac (PNBS) which was used as a curing agent of epoxy was synthesised from phenol novolac (PN) and 1, 4‐butane sultone and confirmed by FTIR and ^1^H NMR. The degree of sulphonation (DS) in PNBS was calculated by ^1^H NMR. The semi‐IPN membranes composed of sul
