ABSTRACT:
An extrusion blow molding process for a heat-treated, liquid crystalline polymer is provided. By the process, molten polymer having improved melt strength, is vertically extruded downward into space through a parison-forming, annular gap. Sag resistant parisons are formed. Beneficially, the parisons may be formed periodically. Advantageously, large-sized parts or structures may be produced.
