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(vinylidene fluoride-co-hexafluoropropylene) Elastomer: Depends on the grade of the polymer. Viton B is used in chemical process plants and gaskets. Zylon: poly-p-phenylene-2,6-benzobisoxazole (PBO) Very high tensile strength and thermal stability: Used in tennis racquets, table tennis blades, body armor, etc.

Poly(p-phenylene) (PPP) is made of repeating p-phenylene units, which act as the precursor to a conducting polymer of the rigid-rod polymer family. The synthesis of PPP has proven challenging, but has been accomplished through excess polycondensation with the Suzuki coupling method. [1] [2]
PBO (Poly (p-phenylene-2, 6-benzobisoxazole)) is liquid crystal polymer developed by Japan-based Toyobo under the trade name Zylon. It is a gold fiber with an initial modulus that is significantly higher than other high modulus yarns, including aramids.
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 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.
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.
