Polymer is thought to be constructing a random structure in molten state. Especially, longer the longest relaxation time, polymer is in a relaxed state with lost the orientation history. Moreover, the amorphous polymer, cooled and solidified from such molten stage is thought to have no structural morphology and show stable mechanical property. However, in this time, we investigated holding time of molten stage dependence to tensile properties by using polystyrene virgin pellet and found that the tensile properties much depends on the holding time and became ductile. And also, we got the results that obvious structural construction were occurred by SAXS and WAXS measurements. These results shows that amorphous polymer construct ordered structure in the molten stage.
