Aromatic sulfonated diester monomer, process to synthesize, polymer derived therefrom and method to prepare said polymer |
摘要 |
A sulfonated dicarboxylic acid and a diaromatic carbonate are reacted by a solution process to form a sulfonated aromatic diester such as dipbenyl sodium 5-sulfoisophthalate. The sulfonated aromatic diester is reacted with an aromatic polymer precursor mixture such as bisphenol A and diphenyl carbonate, polymer or combination thereof, at a temperature above the melting point of the polymer or a member of the aromatic polymer precursor to form a randomly positioned sulfonated aromatic moiety in a polymer chain of a thermoplastic non-crosslinked aromatic polymer such as a linear polycarbonate.
