The morphological structure of cured vinyl-ester resin and the formation of two-phase structures in vinyl-ester resin has been studied by using SEM and differential scanning calorimetry.The results demonstrated the existence of clusters of gel-particles with a size of about 20 μ m,each cluster of gel-particles containing many gel-particles with coral-like structures.The formation of gel-particles resulted in two-phase structure characterized by the two peaks in the rescanned DSC thermographs of the resin. The cure conditions (temperatures,post-cure) affected microstructure in the cured resins.
