Polysulfone. Polysulfone is a commercial polymer that is a product of bisphenol A and 1,1 -sulfonylbis (4-chlorobenzene) (see Polymers... [Pg.153]

Polysulfone. Polysulfone homo- (19) and copolymers have been formed into hollow fiber membranes for hemofiltration by solution extrusion, followed by coagulation and washing. Equilibrium water absorption by these membranes varies between 0.85 and 2.1 percent. The water-equilibrated polymers are glassy at room temperature. Sieving properties of copolymer hemofilters prepared with a 2-phenyl-2-phenoxy propane segment have been characterized (2). The hydrophobicity of this polymer is reflected in a significantly altered rejection spectrum in the presence of protein when compared to saline solutions. [Pg.105]

Polysulfones Polysulfones are aromatic PEs made usually by the reaction of bisphenol A and bis (4-chlorophenyl) sulfone in a nucleophilic substitution condensation reaction. The first polysulfones produced by Union Carbide in the early 1960s involved the reaction of bisphenol with and bis(4-chlorophenyl) sulfone in the presence of an alkali base (NaOH, KOH, and K carbonate) in a dipolar aprotic solvent such as NMP, DMSO, sulfolane, or dimethyl acetamide [78], Typical temperatures are in the range of 130-160 °C. The reaction of the base with bis A generates water, which must be removed. [Pg.285]

The good heat resistance and electrical properties of polysulfones allows them to he used in applications such as circuit boards and TV components. Chemical and heat resistance are important properties for automotive apphcations. Hair dryer components can also be made from polysulfones. Polysulfones find application in ignition components and structural foams. Another important market for polysulfones is microwave cook-... [Pg.105]
