Synthesis and characterization of carboxylated polysulfones

open access: yesBritish Polymer Journal, 1990
AbstractPolysulfone has been carboxylated, via a metalated intermediate, by reaction of a THF solution of polymer with n‐butyllithium and then treatment with carbon dioxide. The polymer reactions with n‐butyllithium were close to quantitative and did not require the use of a tertiary amine catalyst. A series of polymers ranging from 0.2 to 1.9 carboxyl

The Influence of PEG400 and Acetone on Polysulfone Membrane Morphology and Fouling Behaviour [PDF]

open access: yes, 2016
Modification of polysulfone ultrafiltration membrane was conducted by blending polysulfone with PEG400 and acetone as additives. The influence of each additive on the resulted membrane morphology and fouling characteristics were investigated.

Functionalization of Polysulfones by Click Chemistry

open access: yesMacromolecular Chemistry and Physics, 2010
AbstractFunctionalization of polysulfones by using “Click” chemistry is described for the example of a small fluorescent analyte propargylpyrene. First, PSUs were converted to azido‐functionalized polymers by successive chloromethylation and azidation. Propargylpyrene was prepared independently as a fluorescent click component.
