Abstract
Results of Rheotens experiments on a commercial liquid crystalline pol ymer melt are reported. In a nonisothermal extension of extruded filam ents under the action of constant tensile force, we find a maximum mel t tension at break or melt fracture stress of about sigma(B) = 7 MPa, rather independent of extrusion speed or melt temperature.
