Abstract
Thermotropic poly(ester carbonates) such as the terephthalate/carbonate of a mixture of hydroquinose, resorcinol, tert-butylhydroquinone and methylhydroquinone. With a major proportion of the more readily available hydroquinone and resorcinol, thermotropic properties (liquid crystallinity in the melt) are observed.
