Abstract
Time-resolved SAXS has been used to follow isothermal crystallization in the PEO 6000/Resorcinol molecular complex. It has been shown that the complex exhibit crystals with PEO chains in the fully extended form. The initial stages of crystallization are strongly dependent on the temperature : at high supercooling transient once-folded chains crystals are evidenced. They thicken in a single step to give extended chain crystals.
