Ether sulphonates

Schultz et al. for fibre, nylon, cellulose acetate and poly ether sulphone filters [44]. They applied centrifugation as alternative for separation the liquid from the solids. 

As well as the above quoted studies this method has also been used to study the interaction between poly(vinylidene fluoride) and poly(methyl methacrylate) , between poly(ethylene oxide) and the hydroxy ether of bisphenol A ° , and between poly(ethylene oxide) and a poly(ether sulphone) The above equations have also been reformulated in terms of the equation-of-state theory to obtain the interaction energy, which is concentration independent rather than the Flory-Huggins X parameter which is composition dependent.

Table 22 lists four polymer series of PEIs which contain an ether, sulphone or carbonyl linked diphenyl tetracarboxylimide unit [36]. Each of the four series contains two imide and two ester groups and have four aromatic co-monomers. Polymer series 7 and 9 also contain two units of p-aminophenol in conjunction with a bicyclic aromatic dicarboxylic acid, whereas polymer series 6 and 8 are based on m-aminophenol. The Mesogenic Index correctly predicts that series 6, 8 and 9 give rise to isotropic copolymers. However, in the case of series 7, in which the variable monomer was based on ether or thioether diphenol derivatives, thermotropic phases were observed in all three cases. When all four series are viewed as a whole it is clear that an MI value of 9.5 represents a borderline condition for a mesophase to occur. It also corresponds with the minimum value for a mesophase observed in NCPT-based PEIs.

Ether sulphonates are insensitive to Ca ions and water salinity, they are hydrolytically stable, skin-friendly surfactants that are of interest for tertiary oil recovery, cosmetics and chemical specialities [22c, 80]. Particularly, sodium alkylarylethoxypropanesulphonates were supplied by Rohm Haas as Triton X-200 and Triton X-202 .

Polysulphone, Its chemical construction is illustrated in Fig. 1.3. A transparent thermoplastic in its original form. Service temperature of its products is up to about 150 °C. Resistant to hydrolysis (e. g. in repeated heat sterilization). Examples of applications transparent components of medical tools and instruments, electric switches, electronic parts. The industrial polysulphone is poly(ether-sulphone). Trade names Mindel (USA), Udel (USA).
