the fiber is redrawn by stretching the fiber with tension this is usually performed by running the fibers over a set of godets wherein the latter godets are going at a much faster rate than the earlier godets the fiber is elongated at a ratio of between about 1 5 1 and about 10 1 preferably the rate of elongation is 1 foot per minute or less the redraw occurs while the fiber is at or near the temperature to which it was preheated the fiber may be drawn in one or more stages with the options of using different temperatures draw rates and draw ratios in each stage in another embodiment the fibers of this invention may be prepared by a melt spin process in the melt spin process the neat polymer is heated to a temperature between its crystal melting point and the temperature at which the polymer undergoes degradation the particular temperature depends upon whether syndiotactic polystyrene or a mixture of isotactic and syndiotactic polystyrene is used generally the crystal melting temperature of isotactic polystyrene is somewhat lower than that of syndiotactic polystyrene the neat polymer is first melted to a temperature at which the material has sufficient viscosity to extrude the viscosity should be high enough such that the fiber extruded has integrity yet not so high that the polymer is too viscous to be extruded the preferred upper limit on viscosity is 1 u00d7 10 6 poise with 5 u00d7 10 5 poise more preferred and 1 u00d7 10 5 poise most preferred the preferred lower limit on viscosity is 1 u00d7 10 2 poise with 1 u00d7 10 3 poise more preferred and 1 u00d7 10 4.
