“…More recently, similar polysulfonates based on 4,4 -cyclohexane-1,1diyldiphenol and its derivatives [e.g., (61) and (62) as well as chloro-and bromoderivatives (249,250), prepared by conventional interfacial polycondensation, using water-chloroform as an interface, alkali as an acid acceptor, and cetyltrimethylammonium bromide as an emulsifier, have been thoroughly studied (249)(250)(251)(252)(253)(254)(255)(256)(257)(258)(259)(260)(261)(262)(263). In general, the polymers possess good solubility in common solvents, good acid and alkali resistance, thermal stabilities of up to 370 • C, and tensile strength of up to ∼20 MPa (255).…”

Sulfur-containing polymers, when considering their structure, make up a complex group of macromolecular compounds of varied and often remarkable features that determine their versatile applications.The presence of sulfur atoms in polymer structure, depending on the kind of functional group, can improve some important properties, such as mechanical, electrical, and optical, and then adhesion to metals, resistance to heat, chemicals, radiation, and bacteria, biocompatibility, and so on. These are their more important functional groups: sulfide -S-, polysulfide -S n -, sulfonyl -SO 2 -, sulfinyl -SO-, sulfo -SO 3 H, as well as some organic groups containing sulfur atoms, such as thioester -Sulfur-containing polymers can be used as high performance engineering plastics, chemically stable ion-exchange membranes in electromembrane processes, proton-conducting electrolytes, as well as optical, optoelectronic, and photochemical materials. Some polymers are employed in biomedical applications, for example, sulfopolymers as biomembranes and blood-compatible materials, and polysulfates and polysulfonates as antithrombotic or antiviral agents. The presence of sulfur, particularly in the form of disulfide bridges, plays an important role in biopolymers.The purpose of this review is mainly to present recent advances in the area of sulfur-containing polymers that may not yet have commercial applications. Nevertheless, older but still significant material has been included at the beginning of the discussion of each class. Poly(monosulfide)sPolymers containing a monosulfide linkage in both the main chain and the pendent group are the subject of many detailed studies. A few reviews of the synthesis and properties of all types of polymers have been published (1-4); like the one covering polymer with sulfur in the main chain that appeared in 1992 (3). Polysulfides with controlled and well-defined structures can be easily prepared. Nevertheless, the only commercial poly(monosulfide) is Ryton [Philips Petroleum Co., poly(thio-1,4-phenylene) more frequently referred to as poly(p-phenylene sulfide) or poly(phenylene sulfide) (PPS)].

Cardo poly(arylene ether sulfone)s are an important type of high performance engineering thermoplastics. They possess unique properties, including good processability, thermal stability, and good insulating and mechanical properties as well as excellent chemical resistance. They are potential candidates for the preparation of ion exchange, water purification, and gas separation membranes. This review focuses on the synthesis of phenolphthalein-based cardo poly(arylene ether sulfone)s, including synthesis of cardo bisphenols and their polymers, and their application to separation membranes.
