The most important synthetic fiber. They contain at least 85% of polymericester of a substituted aromatic carboxylic acid including, but not restricted to, terephthalic acid and f-hydroxybenzoic acid.

However, its melting point is 148 C. A recently announced thermotropic liquid crystal polymer based on p-hydroxybenzoic acid, terephthalic acid, and p, p'-biphenol has a high melting point of 420 C ...

Phenolic acids, a subclass of phenolic compounds, are known for their diverse biological properties, including antioxidant, antiviral, antibacterial, antitumor, neuroprotective and cardioprotective ...

The researchers attributed this to its high content of benzoic acid derivatives, including ...

Based on the number of aromatic rings in the structure, GP contains three types of polyphenols, namely phenolic acids like hydroxybenzoic acids, flavonoids like anthoxanthins and anthocyanins, and ...
