Synthesis and characterization of polyethersulfone with intrinsic microporosity

Polymers with intrinsic microporosity (PIMs) are usually ladder-type polymers that adopt a spiro structure. In the present study, a new non-ladder-type polyethersulfone-type PIM that incorporates a linear sulfone moiety was synthesized. Brunauer-Emmett-Teller measurements confirmed that the synthesi...

Description
Summary:Polymers with intrinsic microporosity (PIMs) are usually ladder-type polymers that adopt a spiro structure. In the present study, a new non-ladder-type polyethersulfone-type PIM that incorporates a linear sulfone moiety was synthesized. Brunauer-Emmett-Teller measurements confirmed that the synthesized polymer had a high specific surface area (430-590 m 2 g −1 ) due to the presence of micropores of size 0.54-0.66 nm. The intrinsic porosity characteristics of the new PIM are attributed to the resonance structures of sulfone and benzene moieties. Syntheses of new gas-separation membranes using PIMs containing sulfone or similar functional groups are expected in the future. A new non-ladder-type polyethersulfone-type PIM that incorporated a linear sulfone moiety was synthesized.
