Abstract Various poly(ether‐sulfone)s with 1,1,3‐trimethylindan units along the main chain were synthesized from different diphenols and activated dihalogen monomers containing the 1,1,3‐trimethylindan moiety. The indan‐containing monomers were derived from 1,1,3‐trimethyl‐3‐phenylindan by sulfonylation with 4‐halobenzenesulfonyl chloride in the presence of the Friedel‐Crafts catalysts. The polymers are amorphous with glass transition temperatures between 206 and 247°C, and decomposition temperatures above 460°C in air. Due to their solubility in common organic solvents such as tetrahydrofuran and chloroform, the polymers could be fully characterized by gel‐permeation chromatography as well as 1 H‐ and 13 C NMR spectroscopy.
