ABSTRACT:
The present invention relates to liquid crystalline polyesters which have surprisingly low isotropic transition temperatures. The invention further relates to a new process for preparing containers which have more uniform properties made from certain liquid crystalline polyesters. Also, the present invention relates to molded objects comprising certain liquid crystalline polyesters. The liquid crystalline polyesters disclosed herein are derived from 2,6-naphthalenedicarboxylic acid, 4,4'-biphenol, hydroquinone, and p-hydroxybenzoic acid.
