Abstract

Abstract A new sulfonated poly (phenylene sulfone) polymer (SPPS) was synthesized by Diels-Alder polymerization from 1, 4-bis (2, 4, 5-triphenylcyclopentadienone) benzene (BTPCPB) and 4, 4′-diethynylphenylsulfone, and followed by sulfonation reaction with chlorosulfuric acid. A series of sulfonated poly (phenylene sulfone) s (SPPS) with different degrees of sulfonation was prepared in a controllable manner with chlorosulfuric acid. ...
