LIQUID CRYSTALLINE POLYMERS, PROCESSES FOR THEIR MANUFACTURE, AND ARTICLES THEREOF

摘要

Thermotropic liquid crystalline polymers are produced by the reaction of a polyester made from an aromatic dicarboxylic acid and a diol, one or more hydroxycarboxylic acids, a stoichiometric excess of an aromatic diol, and a carboxylic acid anhydride. Also disclosed are novel liquid crystalline polymers that may be produced by this process. These liquid crystalline polymers are useful as molding resins and shaped articles thereof are produced. In particular, the articles include films, sheets, containers and portions thereof comprising these LCPs.
