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.
