The sulphonation of polyethersulphone (PES) with oleums gave sulphonated polyethersulphone (SPES) with high sulphonation degree and solubility in water.Results show that the acid strengths of SPES are in 8.2≤-H0≤11.9 and the catalytic activity and selectivety of SPES are proportional to the sulphonation degree of SPES.The SPES is deactivated rather slowly under experimental conditions.
