Abstract
Disclosed is a process for blow molding articles from liquid crystal polymers containing ionic moieties in the backbone. The ionic moieties increase the melt viscosity of the polymers sufficiently high to blow mold articles therefrom. An illustrative liquid crystal polymer is made from 4-hydroxybenzoic acid, 6-hydroxy-2-naphthoic acid and sodium 5-sulfoisophthalate.
