Synthesis and Properties of Poly(ether sulfone ether ketone)

Abstract

Abstract: Poly(ether sulfone ether ketone)(PESEK) was synthesized from 4,4′-sulfonyldiphenol and 4,4′-difluorobenzophenone through nucleophilic polycondensation. The molecular structure of PESEK equals to alternating copolymer of PES and PEEK. The glass transition temperature of PESEK, belonging to amorphous polymer, is 198 ℃.Its thermal stability and melt flow are better than PES. The results show that PESEK owns good processing property.

Key words: Poly(ether sulfone ether ketone), Poly(ether ether ketone), Super engineering plastics
