Polyphenylene sulfide trade names

Ryton Phillips Petroleum s trade name for its family of polyphenylene sulfide plastics. 

Polyphenylene oxide (Noryl from GE) and polyphenylene sulfide (Ryton from Phillips) are used as high-temperature engineering plastics. Polyphenyl ether sulfones are manufactured by a number of companies under a variety of trade names including 720P, 220P by ICI and RADEL by Union Carbide. They are generally used as injection-moldable thermoplastics and in the adhesive and composite industry. 

Polyphenylene sulfide is a partially crystalline polymer featuring an aromatic ring bridged by sulfur atoms in the 1,4-positions, as shown below. The form presented has the trade name of Ryton. Sample preparation of this material can be difficult, and the traditional KBr pellet method produces a poor-quality spectrum with Christiansen-type distortion (see Fig. 44b). A Csl pellet may be used instead to obtain an improved IR spectrum, suitable for quantitative analysis (see Fig. 44a). This polymer is usually used in conjunction with structural reinforcement additives, such as glass fibers or fillers such as PTFE (Teflon), and caution is necessary when attempting... 

There have been several earlier attempts to make polyphenylene sulfide (PPS), but in the late 1960s, workers at Phillips Petroleum developed the first commercial process [36]. Sodium sulfide reacts with p-dicldorobenzene in a polar organic solvent. Common trade names are Ryton (Phillips Petroleum)...
