Zylon (IUPAC name: poly(p-phenylene-2,6-benzobisoxazole)) is a trademarked name for a range of thermoset liquid-crystalline polyoxazole. This synthetic polymer material was invented and developed by SRI International in the 1980s and manufactured by Toyobo. [2] In generic usage, the fiber is referred to as PBO. [3]
Poly(2,6-diphenylphenylene oxide) reacts with oxidising agents such as chlorine, ozone, nitrogen oxides and sulfur oxides forming acetophenone, benzaldehyde and phenol. Therefore, control of blanks is essential and storage time of samples on poly(2,6-diphenylphenylene oxide) is less than a month.
Poly(p-phenylene oxide) (PPO), poly(p-phenylene ether) (PPE), poly(oxy-2,6-dimethyl-1,4-phenylene), often referred to simply as polyphenylene oxide, is a high-temperature thermoplastic with the general formula (C 8 H 8 O) n. It is rarely used in its pure form due to difficulties in processing.
In organic chemistry, the phenylene group (−C 6 H 4 −) is based on a di-substituted benzene ring . For example, poly(p-phenylene) is a polymer built up from para-phenylene repeating units. [1] The phenylene group has three structural isomers, based on which hydrogens are substituted: para-phenylene, meta-phenylene, and ortho-phenylene.
Poly(p-phenylene vinylene) (PPV, or polyphenylene vinylene) is a conducting polymer of the rigid-rod polymer family. PPV is the only polymer of this type that can be processed into a highly ordered crystalline thin film. PPV and its derivatives are electrically conducting upon doping.

The Federal Trade Commission definition for sulfur fiber is "A manufactured fiber in which the fiber-forming substance is a long chain synthetic polysulfide in which at least 85% of the sulfide (–S–) linkages are attached directly to two (2) aromatic rings."
