Thermotropic aromatic polyester based on p-hydroxy benzoic acid, 4,4'-dihydroxy diphenyl, terephthalic acid, and isophthalic acid

摘要

Thermotropic, fully aromatic polyesters based on p-hydroxybenzoic acid, 4,4'-dihydroxydiphenyl, terephthalic acid and isophthalic acid have exceptionally high dimensional stability under heat. The thermotropic aromatic polyesters are used for the production of moulded articles, filaments, fibres and films.
