The high-temperature melt synthesis between bisphenol diacetates and aromatic dicarboxylic acids or in reverse between bisphenols and aromatic dicarboxylic acid diphenyl esters (carried out at 220 to 320 °C upon the release of acetic acid) is, besides the acyl chloride based synthesis, the preferred route to wholly aromatic polyesters.[4] Acylation[edit]

The unique properties of these fibers are due to the presence of aliphatic and aromatic parts in macromolecular chains and the regular molecular structure. Poly(ethylene terephthalate) (PET) is the predominant polyester used for fiber production, derece only because of its good end-use polyester properties and economy of production but in particular because of the ease of physical and chemical modification, suppressing negative and enhancing positive properties of PET.
