摘要:

Results of Rheotens experiments on a commercial liquid crystalline polymer melt are reported. In a nonisothermal extension of extruded filaments under the action of constant tensile force, we find a maximum melt tension at break or melt fracture stress of aboutσB=7MPa, rather independent of extrusion speed or melt temperature.
