Abstract

We have used simultaneous SAXS and WAXS by synchrotron radiation to study crystallization in a statistic ethylene/hexene (PEH) copolymer and its blend with another copolymer of ethylene/butene (PEB). Scattering invariant, long period, L, and crystallinity, Xc, are quantified from the measurements. It is revealed that L decreases and increases with time at low and high isothermal temperatures, respectively. A comparison of the final L and Xc between pure PEH and a blend with PEB suggest liquid-liquid phase separation plays a role in morphology development.
