Resumen:
In this work, preliminary results of small-angle X-ray scattering (SAXS) applied in epoxy/PHB samples cured at several times are presented.The behavior observed is analyzed as a competencebetween reaction induced phase separation and crystallization of PHB. The peak observed at lowertimes can be associated to the separation produced by reaction but when the crystallization starts, apeak in SAXS spectra associated at lamellar structure is developed. Crystalline regions are developed at blends with lower amount of PHB too, after that phase separation starts.
