Summary
Synthesis of poly(arylene ether sulfone)s with random incorporation of pendant aryl amines was achieved by copolymerization of dichlorodiphenylsulfone (DCDPS) and bisphenol-A with bis(4-fluorophenyl)-3-aminophenylphosphine oxide (amino DFTPPO) with N-methylpyrrolidone (NMP) as the solvent, toluene as the azeotrope and potassium carbonate (K2CO3) as the weak base. A unique feature of this polymerization is that one of the comonomer (amino DFTPPO) contains both an amine functionality as well as activated dihalides which can undergo aromatic nucleophilic displacement by the phenolate, the degree of amination on the main chain can be controlled very precisely by regulating the amount of the amino DFTPPO monomer relative to the other activated dihalide monomer (DCDPS) and bisphenol-A. The synthesis and characterization of poly(arylene ether sulfone)s with various concentration of amine groups on the backbone will be discussed in this paper.
