Polysulfone

A family of themoplastic polymers, like the reaction of a diphenol and bis(4-chlorophenyl)sulfone, forming a polyether by elimination of sodium chloride: n HOC₆H₄OH + n (ClC₆H₄)₂SO₂ + n Na₂CO₃ → [OC₆H₄OC₆H₄SO₂C₆H₄]_n + 2n NaCl + n H₂O + n CO₂.

Chemistry:

Polysulfone allows easy manufacturing of membranes, with reproducible properties and controllable size of pores down to 40 nanometres.

Application: Hemodialysis, implantable ports and membranes for oral bone regeneration.
