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.

La présente invention concerne un procédé pour produire des polymères liquides cristallins thermotropes, par mise en réaction d'un polyester obtenu à partir d'un acide dicarboxylique aromatique et d'un diol, d'un ou de plusieurs acides hydroxycarboxyliques, d'un excès stoechiométrique d'un diol aromatique et d'un anhydride d'acide carboxylique. La présente invention concerne également de nouveaux polymères liquides cristallins qui peuvent être produits selon ledit procédé. Ces polymères liquides cristallins sont utilisés en tant que résines de moulage et permettent de produire des articles moulés. Lesdits articles comprennent notamment des films, des feuilles, des récipients et des pièces de ceux-ci constitués de ces polymères liquides cristallins.
