Abstract
H moiety on each aromatic ring of the polymer backbone; and (d) 0.70 to 1.20 halogen on each aromatic ring of the polymer backbone. The present invention also provides a method for preparing the catalyst including the steps of copolymerization, sulfonation, halogenation, and post treatment. Optimization of the copolymer crosslinking degree, sulfonation and halogenation extent enables the catalyst with a balance of catalysis activity and thermal stability.
